My PLC is WAGO PFC200 Firmware Revision 26. target After updating WAGO_Devices_and_Libraries with newer Firmware 27, CODESYS wants to update all libraries to new versions. I will only add that I did not update the Firmware in the PLC. After compiling the program, I received the following errors: ------ Build started: Application: Device.Application ------- Typify code... [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): FbSerialInterface_internal: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): FbSerialInterface_internal: C0136: Ambiguous use of name 'RTS_IEC_RESULT' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0032: Cannot convert type 'Unknown type: 'RTS_INVALID_HANDLE'' to type 'POINTER TO BYTE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0136: Ambiguous use of name 'RTS_INVALID_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0046: Identifier 'RTS_INVALID_HANDLE' not defined [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_is_tx_empty: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_get_line_state: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_is_line_available: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): COMSW_SET_MODE: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_set_line_state: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' Compile complete -- 10 errors, 0 warnings Build complete -- 10 errors, 0 warnings : No download possible The problem was caused by the WagoSysPlainMem(WAGO) library in the original version 1.5.3.0 after updating to 1.5.3.1. After returning to version 1.5.3.0, the problems disappeared. Probably the version number of this library is responsible for supporting the appropriate Firmware Revision. Can anyone confirm or deny my suspicions?

Post by programmierer on Implementing UDP Communication ^{CODESYS Forge talk (Post)}
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!

Post by rossanoparis on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
Hallo all I would appreciate some clarifications regarding the appropriate runtime system to use. I've been using 'KUNBUS CPUs' and 'CODESYS Control for Raspberry Pi MC SL' for the last 4 years. Recently, there have been some changes in the CODESYS licensing policy. [ https://store.codesys.com/en/howto_applicationbasedlicenses ] My questions are mainly two: 1) If I need to start a new project using 'KUNBUS CPUs', which is the correct runtime system to use. 2) Old projects built using 'CODESYS Control for Raspberry Pi MC SL' should be updated to another RT system? Current RT systems ... a)CODESYS Control for Raspberry Pi MC SL b)CODESYS Control for Linux ARM SL c)CODESYS Virtual Control SL May I count on receiving an explanation to understand the differences among the runtime systems listed above? A detailed and well-organized answer would be greatly appreciated. Kind regards Rossano

Post by lbartik on J1939 TX/RX PDU1 ^{CODESYS Forge talk (Post)}
Is it possible to transmit a PDU1 PGN using the J1939 manager and local device? What if I need to transmit a PGN RQST via 0xEA00 (PGN 59904)? How would I do this P2P (Destination < 0xFF) or broadcast (Destination 0xFF)? I don't think this is possible for any destination type. I don't think it's possible to receive broadcast PDU1 messages either. For example, an address claim PGN 60928 (0x18EEFF80) is addressed to all nodes (0xFF) and not any specific local device so it will be filtered out. These are major oversights in the IoDrvJ1939 library to not support every PDU1 RX/TX scenario. IoDrvJ1939 supported scenario: 1. Receive (RX) PDU1 (P2P) destination-specific (PDU-specific < 255) to local device with matching address IoDrvJ1939 unsupported scenarios: 1. Receive (RX) PDU1 (P2P) global (PDU-specific = 255) 2. Transmit (TX) PDU1 (P2P) global (PDU-specific = 255) 3. Transmit (TX) PDU1 (P2P) destination-specific (PDU-specific < 255)

Post by egau on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
Hi, We have a machine running Codesys on a Windows IPC (CODESYS Control Win v3 - x64). When we hard shutdown the machine, the code on the PLC sometimes becomes "corrupted" after a power on (When trying to login to the PLC, we get the message "The application 'Application' does not exist on device."). I've noticed these errors in the logs, but I'm not sure what to make of them. We are not using any RETAIN variables in our code, although I'm not sure about referenced librairies. (we are using the persistence manager). I'm pretty sure that not doing a graceful shutdown is the root cause of this. This being said, what is the proper way of doing a graceful shutdown? Is putting the Codesys application in "stop" sufficient? I know how to implement this, so if it works then it would be a quick fix. However, I think we need to add a UPS, which would detect power loss and inform the PLC that it needs to initiate its shutdown, and then the PLC would shutdown gracefully. Any help with this will be greatly appreciated :)

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
I have found a very interesting solution using: IoConfigTaskMap IoConfigConnectorMap IoConfigChannelMap The first is the list of IO tasks. The second is the connector for each IO module in the IOMap. The third is the individual input or output on the IOMap. One of the properties of the connector is another pointer to a connector, which corresponds with the connector of the EtherCAT slave. Through this information, it is possible to understand to which EtherCAT slave an IO connectormap corresponds.

Post by annd on Migration von "CODESYS Control for PFC200 SL" zu WAGO FW26 "CODESYS V3.5.19.2" ^{CODESYS Forge talk (Post)}
Hallo, da Wago nun von eCockpit zum offenen "CODESYS Development System V3" wechselt, möchte ich meinen bestehenden 750-8212 von der PFC200 SL auf die Wago Firmware umstellen. Welche Schritte sind dabei notwendig? Den Controller würde ich auf die aktuelle FW 26 updaten und die 3.5.19.2 von Wago mit den Descriptions verwenden. Reicht es im Codesys Projektbaum mit "Gerät aktualisieren" auf den Wago Controller zu wechseln? Es wird dann statt dem "Pfc200Bus"ein leerer K-Bus und ein leerer Com-Port angezeigt. Müssen die einzelnen Module dann darunter neu angelegt und alle E/A Variablen manuell neu eingetragen werden? Das exportieren und danach wieder importieren funktioniert nicht, weil die Namen bzw. Adressen unterschiedlich sind. Ist das so richtig? Kann der Block "Modbus_COM_Port - Modbus_Master_COM_Port - Modbus_Slave" so bleiben wie bisher oder muss das auch unter dem neuen COM-Port neu angelegt werden? Für ein paar Hinweise wäre ich dankbar. Schöne Grüße, annD

Ich hab's hinbekommen: Nach dem Controller Update hab ich ein neues Projekt gemacht und nur den PFC200(8212) eingefügt (es erscheint dann ein leerer Kbus und eine serielle Schnittstelle COM1). Dann hab ich mich am Controller eingeloggt und den Kbus (Rechtsklick: Geräte suchen) mit allen Modulen automatisch ergänzen lassen. Bei den leeren Modulen hab ich dann das E/A-Abbild in csv exportiert. Dasselbe hab ich bei meinem alten "PFC200 SL" Projekt gemacht. Und dann in Excel alle Variablennamen in die leeren csv kopiert und danach wieder im neuen Projekt importiert. Dann hab ich noch alle Programmblöcke, Tasks, Visualisierungen und auch Modbus TCP Master u. Slave und auch Modbus COM Port Master und Slave in das neue Projekt kopiert. Weiters hab ich alle notwendigen Bibliotheken im Bibliotheksverwalter eingefügt. Dann noch ein paar kleine Fehler korrigiert (ich musst einen anderen Block zum Lesen der Uhrzeit nehmen) bis ich das neue Projekt fehlerfrei übersetzen konnte. Dann konnte ich es auf den Wago Controller übertragen und direkt starten. Es sieht so aus, dass alles läuft. Gruß annD

Post by dandyk on Dynamic Images ^{CODESYS Forge talk (Post)}
Hello, I have very similar problem, but it seems that your solution does not work for me. I am using TwinCAT XAE Shell v3.1.4024.55 and TwinCAT Runtime. Sorry for writing here on codesys forge, but since I found the only relevant topic here and since TwinCAT is almost the same with CODESYS in many applications, I chose to write here. I simply need to dynamically update image in visualization based on camera trigger (I am doing a machine vision application). Camera triggers an image, my program processes it (applies thresholding, draws contours etc...) and saves the processed image in the runtime location (the same one you were mentioning). This was done successfully. I need to make it work at runtime, while the program is executing and I need to refresh the image in the visualization each time camera triggers a new image and program processes it. When I create image element in the visualization and define the bitmap ID variable as STRING which contains the image ID defined in the image pool, then it displays the image in the image pool, but does not work at runtime, while the program is executing. I also used the Bitmap Version. I declared it in Global variable list as integer with initial value of 0 and wrote the variable in the bitmap version in the image element in visualization. Each time new image is saved to the runtime location, I wrote a program to increment Bitmap Version by 1. It increments and the image does not update in the visualization, unfortunately. I think that bitmap version is working correctly and deletes the cached image as it is supposed to, but the Image Pool does not update the image ID with the new image... the path to the image is always the same... only the actual image changes with the same file name. Image Pool is not dynamic and cannot refresh the image in the path to the actual one at runtime. How can I refresh the image ID in the image pool at runtime? Bitmap version only deletes cached image and reloads the image from the image ID, but the image ID has the same image, because image pool won't update at runtime. Do you know any solution to this problem?

Post by dwpessoa on CNC Jumps G20 - SMC_NCInterpreter and long time to process ^{CODESYS Forge talk (Post)}
I am studying and developing a Softmotion+CNC system for a machine that executes multiple pieces. The G code program is written by the machine operator and each cycle execute 1 piece. The programs are large, exceeding 1000 lines and using up to 8 axes (X, Y, Z, A, B, C, P and Q). The machine needs to run cyclically, executing N pieces (selected by the Operator)... so I tested it using Looping and counters (G36 G37 and G20) and it worked, but it takes a long time to process, and the more pieces I need, the longer the processing time and this is totally impracticable. I found this solution which was very good, and for a few cycles it works well, but for 99999 pieces of a program with 1000 lines, it doesn't work very well... Another solution I tested is to maintain the interpolator with an automatic restart, that is, I load the program without looping (without G20) and give it another start as soon as it finishes. This partially resolved it, but there is still a delay in processing SMC_NCInterpreter in each restart :(. Another solution I thought of is to manually create the SMC_GEOINFO structure and then reuse it, avoinding the Interpreter, but reading the documentation and checking the structure filled by standard blocks, I noticed that there doesn't seem to be a "JUMP" function in the structure! In other words, the SMC_NCInterpreter actually keeps copying and copying the program section for each jump (G20)... If I repeat a 10-line program 1000 times, I will have a structure with more than 10000 lines... possibly this is the cause of take so long to process. Has anyone ever had a problem like this? I believe the same thing happens with typical applications with manipulator robots using Codesys in continuous cycles, and I would like to know if there is any solution, or even if I am misinterpreting the G20 question in SMC_GEOINFO. Thanks!

Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by timvh on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
I'm not sure what you are trying to do, but getting the CurrentUserGroupID like this will not work, because there could be multiple Visualization Clients and each can have a different user that is logged in. Also when you go online with CODESYS and open an Visualization, this is counted as a client. Probably this is the reason you see it changing. What you can to is "iterate" over all clients and then see which user is logged in on which visualization Client. For this you need to add the Visu Utils library to the project and call the FbIterateClients. See https://content.helpme-codesys.com/en/libs/Visu%20Utils/4.4.0.0/VisuUtils/VisuActionUtilities/Function-Blocks/FbIterateClients.html fbClientIteration( xExecute := x_Execute, itfClientFilter := VU.Globals.AllClients, itfIterationCallback := fbIterator, xDone => x_Done, xBusy => x_Busy, xError => x_Error, eError => e_Error); The fbIterator, in the example above, should be an instance of an FB which you have created yourself and this must implement VU.IVisualizationClientIteration. For example: FUNCTION_BLOCK FB_ITERATOR IMPLEMENTS VU.IVisualizationClientIteration Then automatically the corresponding methods will be called. In the HandleClient Method, you will get an interface to the client(s) and then you can get the current user through this interface: itfClient.UserGroupId You can also get the UserName: itfClient.UserName

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge talk (Post)}
Good morning everyone. In my setup I am trying to use a couple of EL7041-0052 (the EL7041 variant without terminals for an encoder) to run stepper motors without feedback. When using the softmotion drivers for the EL7041 (Rev22 and Rev24, even selecting external feedback type doesn't work) the device log shows warnings for the corresponding hardware: "SDO write error 0x1 -> 0x8012:0x08 eError 0x1 AbortCode 0x6090011". 0x8012:0x08 is the register for the Feedback Type. My best guess was setting the the register value in the start parameters to zero, but the result is the same. What else can I try to get the hardware to work? I have screenshots attatched showing the running fieldbus and the log messages. EDIT: One clarification: the "device log" that shows the error is the PLC, not the ethercat terminal. The log of the terminal itself shows neither errors nor warnings. BR Robert

Post by wbj0t on mobus tcp slave device. read/write holdings with 2 variables. ^{CODESYS Forge talk (Post)}
Hi there. I have an issue to read and set time for the controller. In the issue many registers described as writable by 6/16 functions, and, in this time, also(!) readable! For example: I have time registers: min, hour, day, mon, year. By specifications it is possible check time (so I need always update these varibles in loop) and set time by writing these same registers, BUT how to set, if they will immediatle updated by current time after writing? So, I need to separate one address at two variables. I have seen option mark: Overlay of the process image by the holding and input register. I understand this so: When I READ by function 3, I will get variable that connected with the same INPUT address and when I WRITE by 6/16 this will change second variable that connected with HOLDING address. BUT, this mark doesnt work, when I write 6/16 and try to get by function 3, I will get written value instead INPUT variable. So, what to do?

Post by rabaggett on CODESYS control for Raspberry Pi 64 SL errors ^{CODESYS Forge talk (Post)}
Hi, I am trying to create a project using a raspberry pi, I have added the modules for the Pi and MCP3008. I have encountered som errors that I don't know how to track down. 1. The GPIOs give preprocessor errors, but I read that this does not prevent compiling. This seems to be true. I can build the empty project with no errors. 2. After adding a SPI master and MCP3008, the preprocessor errors double, but seem similar and the project again builds with no errors. 3. I add a DUT and GVL, with a function, and I get the following errors. They remain even if I delete these things. ------ Build started: Application: Device.Application ------- Typify code... [ERROR] crr: C0032: Cannot convert type 'Unknown type: 'ADR(GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7)'' to type 'POINTER TO IoConfigParameter' [ERROR] crr: C0077: Unknown type: 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' [ERROR] crr: C0046: Identifier 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' not defined Compile complete -- 3 errors, 0 warnings I attach the project.

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
Hello, I hope someone could help me. I installed the newest Codesys 3.5 SP 20 Patch 1. When loading the demo files from @i-campbell I can upgrade them to the latest version and everthing works on the OPC-UA client side as expected (object "a" is visible, I can use the "ExampleMethod"). Now I * remove the "Information Model", * delete the "OPC_UA_Symbols Objects", * Add "Information Model" again * add "TestRootObjectType" again and "Generate IEC declarations" * and search for mapped instances (to get instance "a" again) Very good still working as expected. Now I delete the OPC_UA_Symbols and add it again referring to the "objecttest" from 16.9.2020. Also I redo the steps from above. The result is now, that I can't see the "a" object in the "Root/Objects" folder. Why ist this and how can I make it running? I think, it could may be a different version of the UA configuration file. I tried to build my own model definition files and got the same problem (but I am really not an expert). When someone has a actual model, which is also running in the actual Codesys I would be very grateful. Or even better, how to make the correct model in e.g. UA Modeler SW (I followed the description https://documentation.unified-automation.com/uamodeler/1.6.0/html/howprojnet_sec.html).

Post by simone on Cannot connect to webvisu on localhost ^{CODESYS Forge talk (Post)}
As I wrote before on the title, I have difficulties to connect to see webvisu from localhost. The story: while waiting for the plc+hmi to arrive, I'm preparing the software, mainly the visual parts trough the control Win3 x64 (same version as the ide 3.5.20.10). The problem is that I can't see the webvisu with the installed webbrowser. I don't know if this is a problem, but I changed the port to 9001 (randomly "free") because 80, 8000, 8080, 8088, 3000 are all occupied by other projects (all on the Apache server). Is there something wrong with the config file? This is the url: localhost:9001/webvisu_app.htm and here the config file part "CmpWebServer". [CmpWebServer] ;The handling of startup/shutdown of the webserver: ;0->automatically start, shutdown only on shutdown of the runtime;1->automatically start, could be shutdown on demand ;2(default)->start/shutdown on demand;3->start on demand, shutdown only on shutdown of the runtime StartupType=0 ;The TCP port the webserver listens on WebServerPortNr=9001 LocalAddress=localhost ;LocalAdapterName=LAN-Connection LocalAdapterName=EthernetPCPLC ;LocalAdapterNameUnicode=L\00A\00N\00-\00C\00o\00n\00n\00e\00c\00t\00i\00o\00n\00 LocalAdapterNameUnicode=E\00t\00h\00e\00r\00n\00e\00t\00P\00C\00P\00L\00C\00 Thanks for all the help!

Post by denkihitsuji on Content update through Data URI on Web Brower on Visualization Toolbox ^{CODESYS Forge talk (Post)}
Objective: I want to dynamically update the content with strings and JPEG images received from a TCP/IP socket. For this purpose, I am exploring the possibility of utilizing the Web Browser feature of the Visualization toolbox. Example: In a standard web browser, entering data:text/plain;charset=utf-8;base64,SGVsbG8gc3RyYW5nZXI= in the URL window will display "Hello stranger" on the webpage. Issue: When attempting to use this method in the Web Browser of the Visualization toolbox, the content does not display as expected. Instead, it shows the error:'Navigation to the webpage was canceled.'. Request: I seek guidance on how to resolve this issue so that the Web Browser in the Visualization toolbox correctly interprets and displays the data URI content. Alternative Solution Welcomed: Or, if it is possible to directly use Codesys Structured Text (ST) variables within an HTML page, this approach would also meet my requirements. Thank you for your attention.

Post by mubeta on parker servo and position ^{CODESYS Forge talk (Post)}
In general, drives have parameter sets to adjust behaviour in such cases: position recovery, adaptation with resistant torque, out-of-position window failure, etc. (Much depends on the type of configuration set for the axis: positioner, speed controller, torque controller, etc.). I have used that type of drive very little, in only two cases and a long time ago. To tell you what is normal is impossible. I know by reputation they are very simple objects, without too many pretensions and adjustments possible. Try running traces by monitoring actual position, motor current, torque and following error. These are the most sensible curves to understand what is going on. Maybe by fine tuning the motor tuning, the current controller or the speed controller you will get something closer to what you want. For example, from DS, the motor has a standstill torque of 3 Nm. Observe with traces whether this is effective: motor current trend. And afterwards, when you have your own accurate picture of the situation, you can also hear from the product's local support to see if you can steal a few more things from it performance-wise.
