Post by bjarne-pagaard on Codesys v3.5 Sint to byte ^{CODESYS Forge talk (Post)}
Hi A SINT is a short (signed) integer. It is already only 1 byte - so you should have no problem casting it to a byte like so: bMyByte := TO_BYTE(sintMyShortInt); If you have a regular INT you want to put in 2 bytes - there are a lot of ways you can do this. A Union is certainly one of them. You could have a union with 2 memebers: An array of 2 bytes as one member, and an integer value as another member. Another way would be to look at MEMCPY to put the value into your CAN-message. .. or create a function to take your input value as input, and giving you 2 individual bytes as output. This could be handy if you need to change the byte-order. Integer data types: https://help.codesys.com/webapp/_cds_datatype_integer;product=codesys;version=3.5.17.0 -Bjarne

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex

Hello, You use the WAGOUpload tool. You can download it on the download center of WAGO. Make a backup and restore it on the new device. (if can check the remanent data to copy the persistent variables if necessary) You can also use a SD card, go to the WBM copy it the image to the SD card and restart the other controller on the SD card. In the WBM, copy it back to the internal flash. If you contact your local Wago office, they will more than probably help you. There is also a WAGO forum. RP,

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this. Here is my script call: SysProcess.SysProcessExecuteCommand2(pszCommand:='python /home/pi/test.py', pszStdOut:=sCMDOutput, udiStdOutLen:= SIZEOF(sCMDOutput), pResult := ADR(eResult)); Thank you in advance! Best regards, Stefan

Post by miltos on licensing question ^{CODESYS Forge talk (Post)}
Greetings to all, I'm working on a webvisu project on control win V3 x64 runtime, and have purchased 3 licenses for my application. -Codesys Control Standard M -Codesys Visualization L -Codesys Communication M I have them installed on a Codesys usb dongle When I try to download the program, a login error window appears with the message "No valid license found for the webvisualization". The control win v3 communicates with 3 plc, and have enabled communication over codesys V3 communication by adding one datasource for every plc in the datamanager. If I remove the data manager from the project, the rest of the visualisation can be downloaded normally. Do I need to purchase another License and which one? Please find attached the software metrics and the error screen.

Post by mondinmr on Why SysPipeWindows is not implemented in RTE? ^{CODESYS Forge talk (Post)}
This library would be very useful for IPC communications. Using a UDP socket on localhost is unpredictable, as with slightly loaded machines it does not even guarantee packet delivery locally. Using TCP creates a lot of overhead. Message named pipes would be an excellent solution for Windows RTE. On Linux, since the release of the extension package, there is no issue, as it is sufficient to develop a component. However, although now 90% of our clients understand that Linux runtimes are better in every way compared to Windows RTE, especially from the security aspect (Not in kernel space) and the issues with Windows updates, 10% stubbornly insist (sometimes for trivial commercial reasons) on using Windows. Managing IPC with circular buffers in shared memory is quite ugly, or rather really ugly and unaesthetic. In the manuals, I saw the SysPipeWindows libraries, so I decided to test them, but unfortunately, I noticed that they are not implemented for RTE devices. Technically, I could try to open them as regular files, but SysFileOpen returns 16#27 or 16#39 depending on how I set the name (direction of the slashes). Here is the code to create shared memory and named pipes. Shared memory work great, named pipes no! #ifdef Q_OS_WIN32 SECURITY_ATTRIBUTES sa; SECURITY_DESCRIPTOR sd; InitializeSecurityDescriptor(&sd, SECURITY_DESCRIPTOR_REVISION); SetSecurityDescriptorDacl(&sd, TRUE, NULL, FALSE); sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.lpSecurityDescriptor = &sd; sa.bInheritHandle = FALSE; const wchar_t* name = L"Global\\ShmTest"; HANDLE hMapFile = CreateFileMapping( INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, 0, sizeof(SharedData), name); if (hMapFile == NULL) { qCritical("Error creating shared memory"); return 1; } data = static_cast<SharedData*>(MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, sizeof(SharedData))); if (data == NULL) { qCritical("Error mapping shared memory"); return 1; } HANDLE hPipe = CreateNamedPipe( TEXT("\\\\.\\pipe\\MyPipe"), PIPE_ACCESS_DUPLEX, PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, 1024 * 1024, 1024 * 1024, NMPWAIT_USE_DEFAULT_WAIT, &sa); if (hPipe == INVALID_HANDLE_VALUE) { qCritical("Error creating named pipe"); return -1; } if (!ConnectNamedPipe(hPipe, NULL)) { qCritical("Error connecting to named pipe"); return -1; } checkPipe(hPipe); #endif

Post by serwis on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

Post by struccc on Wish: CODESYSControl.cfg - again ^{CODESYS Forge talk (Post)}
Before creating this topic, I was browsing the search results for CodesysControl.cfg - many results, and I remember very well, it's a problematic issue for a long time. To summarize: there were many requests for documentation on this file - the most comprehensive reply is: https://forge.codesys.com/forge/talk/Runtime/thread/ebbf851a3d/#eb85 Hi, not really, this is covered by the manual which you get if you use a runtime toolkit which is not free of charge. Maybe we need to extract the config file part from that documentation if that is possible. BR Edwin I am not sure how much is this relevant, since we buy SL License directly from CODESYS... I think it is a reasonable demand, to get documentation on the configuration entries affecting the documented behaviour of the runtime system and it's components The actual reason I bring up this issue again can be read here: https://forge.codesys.com/forge/talk/Runtime/thread/febad3cc40/#0e12 but mostly my frustration about noticing some new, unknown and undocumented entries in my configuration file. Again. And this happens a lot recently. Just some examples: Changes with SysFile - and mandatory use of IEC path Introduction of Mandatory user management File transfer service now disabled by default SysProcess - allowed commands The above mentioned CmpApp parameters... And finally (Regaridng windows install): With the newer versions, the installation directory (together with the configuration file) tends to hide itself to some super silly location under the roaming profile data of local system account. I am not sure if this change was documented somewhere, but was a very unpleasant one. Someone could please explain the reason and the concept of the introduction of this release specific directories (I am sure, there is a good reason) - how to use them properly? - How to re-introduce user configuration (to preserve configuration data between versions)? - How to do version - to version migrations properly? - How to keep old version of runtime available and ready to start with it's original configuration and application? - ... Therefore, the lack a regularly updated description of CodesysControl .cfg , including all the configuration entries, together with their default values for different runtime versions is really a big deficiency.* This should be done for all components storing or just seeking data from this file... (Maybe there is such thing but I failed to find???) It is regularly causing trouble when introducing a new version (together with the long awaited bug fixes and enhancements), what has changed it's default behaviour for security or other practical reasons. I agree this is very important, and it is logical to change the default options: But it must be documented historically, and make it easily available, so we can prepare better for the upgrade of the runtime. Forge talk is a great source, but not very practical for this kind of documentation purposes... Thanks in advance for CODESYS staff 🙏🙏🙏 (Ps.: It would look rather silly, if some members of the user community prepares this documentation on a Forge Wiki page... Or??? Should we?)

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Hi Everyone, For a fast monitoring system I am using Ethercat oversampling and timestamping inputs. As the customers has a lot of different configurations out in the field, we went for a dynamic Ethercat configuration. Already got the whole detection chain working but now I am stuck since two days in debugging the configuration. Here are my quesitons: I extended the dynamic config example for the EL3632 16#0E303052: //EL3632 pSlave^.SetDCSettings(TRUE,TRUE,80,80,TRUE,4000,0,0); pSlave^.AddSyncManager(16#1000,128,16#26,TRUE,3); pSlave^.AddSyncManager(16#1080,128,16#22,TRUE,2); pSlave^.AddSyncManager(16#1100,0,16#4,TRUE,1); pSlave^.AddSyncManager(16#1110,214,16#20,TRUE,0); pSlave^.AddFMMU(0,214,0,7,16#1110,0,1,1); pSlave^.AddFMMU(0,1,0,0,16#80D,0,1,1); xKnown := TRUE; This leads to a PLL Error for these devices. I double and triple checked the configuraton, but cannot find the issue. There seems to be one difference: the config dialog creates a startup parameter: 16#10F3:16#05, Name: Command_0, Value:0. Bitlen: 16, Stop on fault: false, jumpt at fault: false: next line: 0 a) I do not find information on how to set this in my code. Can you help me there? b) Without trying to set the value, I get a PLL error for these devices in the master log. Is the config wrong? c) Do I need to set the Master to Autoconfigure or Manual? I used autoconfigure for my tests. The stack creates input data addresses for the slaves input data range (pSlaves[i].InputData) which are different from those created when I use the Engineering tools dialogs to configure Ethercat. Specifically, the addresses seem to be aligned at 16 byte boundaries when they are created using the engineering tool, but may appear at uneven addresses when I use the script in dynamic config. I did not try to access ULINT at uneven addresses yet, but I am suspecting this may be a problem. Do I need to manually align the addresses ? Any help is appreciated...

Post by struccc on Application failing to boot after system reboot ^{CODESYS Forge talk (Post)}
I started to experience the same issue, after upgrading to 3.5.19 , and still persists with 3.5.20.3 , using CodesysControlWinV3 x64 on Windows. Unfortunately, this is a live application, normally it is running for months without interruption - so it was a surprise at the last cold start... It was not possible to go online with the original version, so I couldn't see the application, or system status, just the log message. First time I manually clean the Application from the PlcLogic directory (there was no coredump file in there), then I could start the runtime service, and do a fresh download, and set the bootproject. I could not try a cold system reboot - it's in a 24/7 production environment, and I was under heavy pressure to start... What I did, I have created a backup from the * complete * runtime directory, from the failed, and fixed version - before and after download. This directory in my case C:\ProgramData\CODESYS\CODESYSControlWinV3x64\55096128 - At the next shutdown, it was sufficient to copy back this backup completely, and could start the runtime service afterwards. Ugly, but local staff with some skills can do it without programming tool... I don't store any live data, configuration, log files, persistent data in this directory - the only reason I need this is to edit the CodesysControl... .cfg file.... And to see the logfiles in emergencies like this. The application concerned doesn't use any retain area. - exactly for these reasons - Maybe that is causing the problem with the newer runtime versions As far as I see, this problem occurs only if the power of the Windows PLC is interrupted without a proper shutdown. Unfortunately, this can happen sometimes. The newer versions, seems tp modify CodesysControl.cfg on the fly, and register the applications, and bootproject information after download. (I don't really see CodesysControl.cfg a proper location for this... but that's just my feeling) So now I had a look at CodesysCotrol.cfg on my laptop and I found: [CmpRetain] ;Retain.SRAM.Size=0x200200 ;Retain.SRAM.Address=0xFA3C5776 ;SimulateSRAM=1 [CmpApp] ;Bootproject.CreateOnDownload=0 ;Bootproject.StoreOnlyOnDownload=0 ;Bootproject.InvalidateByRename=1 ;Bootproject.InvalidateBySetting=1 ;Bootproject.InvalidateNever=0 ;PersistentForce=0 ;RetainType.Applications=InSRAM ;RetainType.Applications=OnPowerfail ;RetainType.Applications=None ;Exception.Hardware.GlobalStop=1 Application.1=MyTestAppNoRetain The last line appeared after download and boot project creation. Maybe... Should set RetainType.Applications=None? I wonder about all these settings, but... Will write separately about it. I hope this helps a little...

Post by eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

Post by solidlogicguy on Little endian to Float from Modbus RTU ^{CODESYS Forge talk (Post)}
Hello, I got a device from which I require to read values from I am using a WAGO PLC 750-8212 and I am communicating through Modbus Master FUNCTION BLOCK from library WagoAppPLCModbus in Codesys 3.5 to this device. I already receive data from the device that is a CVM to monitor voltage from a fuel cell. The technical support of the company that makes these devices says that the data is sent in little endian form. And I want to convert it to a float value. The tech support sent me the next instructions of how to do it but I am new using codesys, so any advice or help I will really appreciate so much. Message from tech support: The process is complicated, better to do it with already implemented library in the language/program you use. Basically the process should be next: To convert the two Modbus registers containing parts of a 32-bit float in little-endian byte order to a floating-point number using mathematical operations, you first need to combine the two 16-bit integers (assuming reg1 is the lower word and reg2 is the higher word) and then interpret the result according to the IEEE 754 standard. Given: - Register 192 (reg1) = 4096 - Register 193 (reg2) = 14884 Step 1: Combine the two registers. Since we are dealing with little-endian byte order, reg2 is the high word, and reg1 is the low word: combined = reg2 * 2^16 + reg1 combined = 14884 * 65536 + 4096 combined = 975175680 + 4096 combined = 975179776 Step 2: Convert the combined value to binary: combined_binary = '1110101101011100000000000000000' Step 3: Split the binary into IEEE 754 components: Sign bit (1 bit): 0 Exponent (8 bits): 11101011 Mantissa (23 bits): 01011100000000000000000 Step 4: Convert the binary exponent to decimal and subtract the bias (127 for 32-bit floats): exponent = int('11101011', 2) - 127 exponent = 235 - 127 exponent = 108 Step 5: Calculate the mantissa as a fraction: The mantissa in IEEE 754 format is the fractional part after the leading 1 (which is implicit). Therefore, we need to convert the binary mantissa to decimal and add the implicit leading 1: mantissa_fractional = 1 + int('01011100000000000000000', 2) / 2^23 mantissa_fractional = 1 + 18688 / 8388608 mantissa_fractional = 1 + 0.002227783203125 mantissa_fractional ≈ 1.002227783203125 Step 6: Combine the sign, exponent, and mantissa to get the float value: float_value = (-1)^0 * mantissa_fractional * 2^exponent float_value = 1 * 1.002227783203125 * 2^108 Because the exponent is quite large, the resulting float value is a very large number.

Hi All, Recently I have been experiencing a issue in CodeSys SP16 Patch 3, with a exception which comes up after I have made several online changes. callcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008, after I experience this fault then I receive a error message for any subsequent online change "online change failed, no task gap within 10000ms". To recover either the controller needs a orgin reset, which will allow online edits thereafter until falling back into the loop. I am using a TURCK TX707 product which is controlling robot trajectory, We have hard coded the coordinate data rather than using persistence variables so hence the need to do online changes consistently. I have read on the forum other people have experienced similar issue with the online task gap, but I have no task which have same priority and also monitored the CPU usage and have not seen it go above 13%. Anyones help would be much appreciated, thankyou.

I am able to connect and read the sensor data when running a python code locally. However in Codesys, I encounter this error "A bus error has occurred." and "There was no response in time". Could this be because of Modbus Server Channel and Modbus Server Init configuration on my part? Admittedly I am new to Codesys. To get to this stage, I: 1. added some lines to CODESYSControl_User.cfg 2. added "Modbus_COM" in Codesys and set "Serial Port Configuration" under "General" 3. added "Modbus_Master_COM_Port" in Codesys and checked transmission mode is set to "RTU" 4. added "Modbus_Slave_COM_Port" in Codesys and checked server address is set to 1 (also set 1 in my sensor) 5. added 1 channel and 1 init for "Modbus_Slave_COM_Port" under "Modbus Server Channel" and "Modbus Server Init"

Post by trusty-squire on CNC - How to manipulate SMC_GeoInfo objects ^{CODESYS Forge talk (Post)}
I have an application using CNC GCode interpolation, but I need to modify the GCode provided to the PLC based on certain parameters. I am currently attempting to modify the SMC_GeoInfo objects in the SMC_OutQueue using the code below. Note that all the other code is pretty standard and works fine, but when I add the below it errors. PROGRAM TEST VAR fbReadCncFile : SMC_ReadNCFile2; fbCncInterpreter : SMC_NCInterpreter; arrCncInterpreter : ARRAY[1..99] OF SMC_GeoInfo; pGeoInfo: POINTER TO SMC_GeoInfo; giGeoInfo: SMC_GeoInfo; // ... END_VAR // ... Some code here in order to read CNC file using SMC_ReadNCFile2 and provide to SMC_NCInterpreter pGeoInfo := SMC_GetObj(poq:=ADR(fbCncInterpreter.poqDataOut), n:=1); IF pGeoInfo <> 0 THEN giGeoInfo := pGeoInfo^; // Do some manipulation here, then update the queue at the same position MC_SetObj(poq:=ADR(fbCncInterpreter.poqDataOut) , n:=0 , pgi:=ADR(giGeoInfo) ); END_IF It throws an error when I get to the line giGeoInfo := pGeoInfo^; Error: EXCEPTION [AccessViolation] occured: App=[Sim.Device.Application], Task=[PathTask] How do I use SMC_GetObj and access the data? It creates a pointer with the value as shown in the photo, but all the dereferenced values say dereference of invalid pointer.

Post by bruceae on Ethernet/IP Scan ^{CODESYS Forge talk (Post)}
Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

Post by codesysbeginner on Eaton XC303 - USB Mounting / Trend manager ^{CODESYS Forge talk (Post)}
Hi, For a project I am using the trendmanager functionality, I changed the placeholder filepath to which the SQL database is saved to: home/disk_usb, $trend$. Which only works as long as the usb was mounted to the PLC at boot. However, I'd like to be able to switch the USB's out if they break or for data analysis. However when a new (or the same) USB is plugged back in the shortcut doens't exist on the device anymore. Also in the device directory under root/mnt/ a new folder appears SDB1 in addition to SDA1 to which the Trendmanager was originally writing. The SDA1 folder is empty/unreachable while the new SDB1 folder has the contents of the USB drive. I tried disabling the trendmanger while unplugging the USB's however this doesn't work. My question, how do I make it so that when I plug a USB drive back in, it will be mounted to SDA1 instead of SDB1? Kind Regards

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register

Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Hello Everybody, I have created a project for an Eaton XC303 that sends lots of data to a router via UDP. It works fine. However, when there is more than one product connected to the router, then it is necessary to change the IP address of the Ethernet port 0, from e.g. 192.168.2.11 to 192.168.2.12 (second product). It is easily done via PLC Shell (setipaddr 0 192.168.2.12), but the people in production is struggling with the PLC Shell commands and I would like to create a Visualization page that will hide that. I used the instruction: eChangeIPResult:= SysSockSetIPAddress(strEthernetPort, strIPAddress); and it works, until the PLC resets. I already read some posts and it appears that I need to stop the Ethernet 0 port and Reconfigure it, but I am really struggling to find the right way to do it. Any help will be much appreciated.
