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 critcho on WebVisu Numpad dialog - Dialogtitle not accepting string variable ^{CODESYS Forge talk (Post)}
I have a WebVisu page which is re-used for multiple types of gas; it displays the alarm thresholds etc. for one gas at a time. I have an array of structures holding the set-points for each of the gasses. I'm trying to change the dialog title for the value input pop-up (VisuDialogs.Numpad). The Dialogtitle is set to Gas_Alarms.HighAlarmActivationLevelDialog, which is a string(50): When the gas type is changed (page first loaded, or prev/next buttons), METHOD Gas_Alarms.Update_Display_Variables is called, to update the strings used for the dialog titles so it shows GasName High Alarm Activation Level (EngineeringUnits), e.g. CO2 High Alarm Activation Level (PPM): HighAlarmActivationLevelDialog := Insert(' High Alarm Activation Level ()', EngineeringUnits, 30); HighAlarmActivationLevelDialog := Insert(HighAlarmActivationLevelDialog, GasName, 0); (That's not where the problem is, I'm just explaining why I'm using a variable dialogue title.) The variables used are definitely strings, but i'm always getting the error: "The type of the dialog title must be either STRING or WSTRING". I've tried moving HighAlarmActivationLevelDialog etc. to the GVL and also changing them to WSTRING, I even tried adding them to the structure array, but I always get the same error. Clearing the dialog title for that element removes the error - so I'm confident it's not a phantom error caused by something else. But I should be able to add these titles, can't just nuke them all to make it work. The MinVal and MaxVal for the Numpad are called from the array, e.g. GVL.Gas_Alarm_Configs[0].ScaledValueMIN, they are not getting an error. I am using array indexes 1 - 5 for the gasses, when I load the form or change gas, I copy the selected index to index 0 of the array, and values from Gas_Alarm_Configs[0].[ALL] are displayed on the page. When they hit save, I copy Gas_Alarm_Configs[0].[ALL] to Gas_Alarm_Configs[CurrentGasIndex].[ALL]. (ALL just means every element, I can't figure out how to display an asterix in this question... :) ) I've searched online for variable title dialog, but not found anything to help. Thanks for your help!

Post by smeitink on Timeout Error in Modbus Communication with WAGO PFC200 and iEM2050 Meter using 750-652 Module ^{CODESYS Forge talk (Post)}
Hi all, I'm looking for help with an issue I've come across while trying to facilitate Modbus communication between a WAGO PFC200 PLC using a 750-652 communication module and an iEM2050 Series Single Phase Energy Meter. I believe to have everything wired and setup correcty, but I keep running into a "Error time out" message, and by now I don't really know what else to try. My setup is as follows: A PFC200 Wago PLC, which has 2 750-652 Serial Interfaces extension modules connected to its field bus. I'm using one of these to talk to a Schneider iEM2050 - kWh-meter over modbus. I have connected terminal 23 (A) of the iEM2050 to connector 6 (A) on the 750-652. I have connected terminal 24 (B) of the iEM2050 to connector 2 (B) of the 750-652. I'm using 200mm of twisted together wires to connected them both, and I have placed a 120 ohm resistor between A and B at both ends. I've attached relevant pinout images to this post. I then wrote a simple program that configures the Mobus port, as per the datasheet of the iEM2050. You can find an image of the relavent page attached to this post too. This is my program: PROGRAM PLC_PRG VAR Master: FbMbMasterSerial; xIsConnected: BOOL; xError: BOOL; iIndex: INT := 1; xTrigger: BOOL; utQuery : typMbQuery := ( bUnitId := 1, // The Modbus unit or slave address bFunctionCode := 4, // Function code for reading input registers uiReadAddress := 1829, // adress for the Power on off counter uiReadQuantity := 1 // Quantity of registers to read ); iStep: INT; oStatusModbus: WagoSysErrorBase.FbResult; utResponseModbus: typMbResponse; xConnect: BOOL := FALSE; delayTimer: TON; END_VAR Master( xConnect:= xConnect, I_Port:= _750_652_24_1, udiBaudrate:= 9600, usiDataBits:= 8, eParity:= WagoTypesCom.eTTYParity.Even, eStopBits:= WagoTypesCom.eTTYStopBits.One, eHandshake:= WagoTypesCom.eTTYHandshake.None, ePhysical:= WagoTypesCom.eTTYPhysicalLayer.RS485_HalfDuplex, xIsConnected=> xIsConnected, xError=> xError, oStatus=> oStatusModbus, eFrameType:= WagoAppPlcModbus.eMbFrameType.RTU, tTimeOut:= T#5S, utQuery:= utQuery, xTrigger:= xTrigger, utResponse:= utResponseModbus); delayTimer(IN := TRUE, PT := T#3S); // Use the Q output of the timer to set xConnect after the delay IF delayTimer.Q THEN xConnect := TRUE; END_IF CASE iStep OF 0: //Wacht totdat de master de poort geopend heeft IF xIsConnected THEN iStep := 1; END_IF 1: //Stuur request naar de slave xTrigger := TRUE; iStep := 2; 2: //Wacht totdat de master klaar is met het afhandelen van de request IF NOT xTrigger THEN iStep := 3; END_IF END_CASE The TON delay before opening the port is due to a an error I encountered when opening it straight away. This seems to be a bug, as described here. However, the TON solved that particular issue. I tried reading multiple registers, but like I said, I still always end up with the "Error time out". What else can I test or try at this point?

Post by arnaud on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
Hi there! I'm using eCockpit WAGO software to develop HMI's for multiple projects. As I recently starting this, my knowledge on the software is somewhat limited (so maybe my question is a simple one). For most of my projects I can simulate the application and start it to test the code and HMI. However for two projects, I can initiate the "simulation activation" but I cannot start it. Nothing happens when I press start and the visualization shows "The online visualization is waiting for connection. please start the application". - I don't see any errors in the messages - Initially the project are made by a colleague, which moved on. I guess I'm forgetting something, like missing a setting. I appreciate any help I can get. If you need more information to help me out, let me know. Thanks!

Post by smartcoco on The text list provided outside the library is not available for visualization controls within the library. ^{CODESYS Forge talk (Post)}
I have a project called 'DemoProject' and a library called 'DemoLib'. Create a visual control named "DemoVisu" in the library, with a selection box of type "ComboBoxInteger" in the space. Now 'ComboBoxInteger' requires a 'Text list'. This "Text list" is provided when I call the "DemoVisu" control of the "DemoLib" library in "DemoProject". And this text list is in 'DemoProject'. I found that 'ComboBoxInteger' no longer works at this time. Other visual controls that use text lists also have this issue. I hope there is a good solution to this problem.

Post by gurke258 on Codesys Safety EtherCAT with Beckhoff ^{CODESYS Forge talk (Post)}
Hello :) We are currently configuring a system with Codesys as SoftPLC on a Linux system and with Beckhoff terminals. I have already gained some experience with Codesys and also with TwinCat incl. TwinCAT Safety. What is new to me now is Codesys in conjunction with Beckhoff safety terminals. We are currently using an EL1918 & EL2904 here. I have been able to integrate both terminals into my project, but I don't know how to interconnect them so that they communicate. That's a bit easier with Twincat ^^ Can any of you help me? I would also prefer a Codesys EtherCAT Safety training or webinar if anyone knows of one. Unfortunately I can't find such an event on the internet.

Post by kunz on Responsive Design Example ^{CODESYS Forge talk (Post)}
Hello everyone, I have a problem with the example project Responsive Design Example, which is available here in Codesys Forge. I wanted to try switching the visualization depending on the device type. To do this, I used a smartphone to access it. I can see via breakpoints that the Smartphone visualization is selected, but the visualization of the normal monitor still appears on the smartphone. Could there be a problem with the libraries, or why is the device not assigned the correct visualization page? I dont know how do further debuggin or troubleshooting. Here the page to the example: https://forge.codesys.com/prj/codesys-example/responsive-desi/home/Home/ Thank you very much.

Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Hi @tk096, Thank you for your response. Here is example project file and some screenshot for your analysis regarding this matter. In order to reproduce the problem on your side and make it independent of the hardware, I simulated the encoder counter incrementally for the master in this example. I configured a virtual axis as the slave motion axis. The problem occurs in the same way in the real hardware configuration (servo drive connected to Ethercat and hardware incremental encoder) in MC_CamIn. I hope this example helps you see the problem on your side and understand and find the source of the problem with FreeEncoderAxis for Softmotion 4.17.0.0. Best Regards, Imdat

Opening the .ret file content in a hex editor (I only use a single string retain var) I asked myself what the meaning of the first 24 bytes is. It neither contains a handle to the application nor a reference to the variable. Is this maybe a timestamp? Or a CRC/checksum? Regards, Thomas

I tried to delete the TextLists, delete the combo box, to clean the project, but the error still there. How can I delete this option (2,Recipe #2)? Or how can I fix this error?** Thank you.
