Post by rossanoparis on How to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server ^{CODESYS Forge talk (Post)}
Hello at all I'd like to know how to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server. In the past, I tried to ask in "Forge" about this topic, but I could find neither help nor document informations about it. Reading the file "codesyscontrol.log" I see these logs OPC UA Server Started: Hostname: NTLRPICTRL01, Port: 4840 URL: opc.tcp://NTLRPICTRL01:4840 Loopbackadapter activated. **All available networkadapters are used.** Multithreading activated. 3 workers used. My controller, which is a Linux PC, has got two network cards eth0 and eth1 I whant to use the card with name "eth0" as a server for OPCUA and keep the "eth1" free for other stuffs. Is it possible ? Best regards Rossano

Post by muhq on Profinet connection to Siemens CP343-1 Lean (IO-Device/Slave) ^{CODESYS Forge talk (Post)}
Hi, I am quite new to Codesys and I try to do a Profinet connection to an Siemens PLC (315-2DP) with CP343-1 Lean Modul. I already configured the Siemens PLC, exported the GSDML. Then I added a new project in Codesys, added following moduls: - Ethernet - PN_Controller - Imported Profinet Device via GSDML importer When I start the programm everything looks fine but I always get the message "Stopped Profinet" and no data is available This is only for a small test. Therefore I start to do that on a Windows 10 with Development System. Later I will try to realize this on Raspberry. Ethernet Adapter is configured (192.168.1.1 / 24) Firewall deactivated WinPCap is installed S7-Station seems to be found ('fuadazenzitest') Can please somebody help me?

Post by tvm on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
ok, that's different than our issue then. We're using Schneider Electric M262 PLCs, and we've had it where certain web browsers cause the web server to only allow https connections, but it's not recoverable with a refresh. It usually requires a power cycle or even a full firmware flash. Your issue might have more to do with the timing. I don't know if it helps you, but we normally run our visu task at 200mS, with an update rate of 200mS. Seems to work. I went through this: https://faq.codesys.com/pages/viewpage.action?pageId=112525371 but it really seems like trial and error.

Post by andrej on Threads and TID created by CODESYSControl Win V3 ^{CODESYS Forge talk (Post)}
Hi all, for a deeper understanding of the Codesys RTE - I created a simple application with 3 IEC tasks (Ta,Tb,Tc) each with different priorities, and different cycle times. The application runs on Windows 10 in the Soft PLC CODESYS Control Win V3. If my understanding is correct, the RTE i.e. the Process CodesysControlService should spawn 3 threads (Th_a,Th_b,Th_c) which are executed with the defined cycle times, the priority of the threads should reflect the priority of the task set in the Codesys IDE. Does somebody have an idea, how I could identify the respective threads in Windows? Kind regards Andrej

Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

Post by macros8 on Alarm Management - latched variable represented as Text list ^{CODESYS Forge talk (Post)}
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

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 ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Post by bahrt on Raspberry Pi GPIO mapping ^{CODESYS Forge talk (Post)}
Hi I am about to configure ALL GPIOs on a Raspberry Pi 3 model B V1.2. It seems that I have limited understanding of why not all the IO’s become available with the corresponding mapped IO’s – the 'dwInUse' contains mapping of the inputs from GPIO0 to GPIO27. But 'dwInputs' are only showing GPIO0 to GPIO8 and GPIO15 as available inputs. These mentioned inputs work fine You will be able to watch the limited mapped IO activity here: https://drive.google.com/file/d/1zz4PBNBfRZBF2YkiJ2VQxw6L9MBVji7R/view?usp=sharing Can you please bring your best idea on why GPIO09 to GPIO14 and GPIO16 to GPIO27 state are not active (at a fixed zero state) in the dwInputs register? Thanks in advance. Best regards Andreas Bahrt

Hi guys I am trying to run on my laptop Codesys 3.5.19 Control Win x64 where I created a EtherCAT master. I have defined the controler, specified network adapter (my docking station) and everything worked as expected. Later I needed to test it on site (without docking station) so I changed the network adapter by EC master to my laptop network card. After that it shows "Network adapter opened" but no device can be found by scanning and in LOG is saying "SysEthernet: packet could not be sent, error code: -1". Same error with USB network card, but if I switch back to docking station, all is working again... Any idea what I'm doing wrong?

Post by riccardo on Codesys SP19 patch 4 ^{CODESYS Forge talk (Post)}
Hallo everyone, I am working on new PLC of Weidmueller that uses Codesys SP19. I made the upgrade at the Patch 4 coming from patch 0. Unce made the upgrade everything is working well in the progect except the web visu user menagent. In the new version, when I perfom the login, I cannot use the keyboard of the device; the window where to digit the user name and password opens, the buttons "OK" and "Cancel" work but the system doesn't allow to put input from the device keybord, the mouse behaves as it is an image. If I active the virtual keypad or numpad it works otherwise nothing. I am wondering if it is a bug of the new package or if I must set something else. Thanks in advance, Riccardo.

Post by mahmutbeyaz on Create a Motion Profile ^{CODESYS Forge talk (Post)}
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.

Post by jmorit on CAM Table - Quadratic velocity ramp with jerk limitation ^{CODESYS Forge talk (Post)}
Hello, I'm working on setup a CAM table by using the Codesys CAM Editor. My purpouse is to obtain a quadratic velocity ramp with jerk limitation motion profile, for which i define the accel/decel phases with Poly5 segment type, but the problem is that due to the fact i can "only" adjust until the acceleration, and the jerk is always setup to 0, and i cannot change the jerk values, i cannot achieve the desired results, as i need to generate jerk steps. Is there any way it can be achieved with the editor, or maybe by using PLC runtime code? Thank you in advance for your help BR, Jordi Morito

Post by dkugler on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
I would figure out, how to create a simple html webpage with 2 frames. One frame with buttons to select the plc. A second frame with hyperlink to the webvisu of the plc ("XXX.XXX.XXX.XXX:8080/webvisu.htm"). Selecting other PLC Button has to change the hyperlink in 2. frame. Costs only some time to figure out :-) Or setup a raspberry Pi with small visualization. Set up a button for each plc and add one browser element. Each button writes the URL of the depending plc to the URL setting of the browserelement. Costs 55€ for runtime licence and a Raspberry Pi.

Post by hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable.

Hi, maybe this fixes your problem. At least this was our issue back then. We tried to run the codesys runtime environment on an embedded Linux system. The problem on our side was that we changed the WORKDIR directory in the /etc/init.d/codesyscontrol script to /home/user/codesys, but we forgot to copy all files (including the hidden files) from the initial WORKDIR (I am not sure but I guess the initial WORKDIR was /var/opt/codesys) to the new one. After copying those files and restarting codemeter and codesyscontrol, we were able to upload licenses. Hope this help BR Josef

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by amy123 on Alarm Manager Example Alarm Client doesn't Populate ^{CODESYS Forge talk (Post)}
Hello, I tried to run the example project from https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ However, I can not get the interface for Alarm History 12 Alarm Manager client to populate with any alarms. 'udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClient12, ADR(arritfAlarmsFromHistory12), iMaxCountAlarmsFromHistory12);' when I look at itfAlarmManagerClient12 its always empty. What is confusing is that when I simulate 2 alarms, iCountActiveAlarms 12 has a vlaue of 2, associated with itfAlarmManagerClient12 - so that appears to work. And yet, its useless as the ProcessAlarms Function can't extract anything from the empty array. I dont understand how these arrays are supposed to be populated and why its not working. Any help would be greatly appreciated!

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.
