Post by c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Post by lukebouchard on NVL generating ADwin packets instead of UDP? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5 SP11 32bit to program a pair of IFM CR711S controllers. They each have an NVL sender and are set up to receive each others messages. One is transmitting properly but not receiving, the other is receiving the first's messages just fine. When I look at the traffic in wireshark, I can see the one transmitting properly as UDP packets on the subnet and port I had specified. The Second is transmitting on the right subnet and port, but is sending 'ADwin Config' packets. Has anyone run into anything simmilar? From some reading on ADwin from google, nothing is enlightening. Both are set up in the same way, have their own ports and List Identifiers. I have deleted the NVL files and regenerated them, cycled power, and even deleted and remade the NVL's so many times.

Post by jonathan1321351 on IO-Link write parameters Ethernet/IP ^{CODESYS Forge talk (Post)}
I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Post by trusty-squire on How to revert to previous version library ^{CODESYS Forge talk (Post)}
Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

Post by dkugler on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
you can give this code snippet a try. It's extracted and simplyfied from my code: Install VisuElemBase lib if not installed yet. Execute in visu task: VAR pClientData : ARRAY [-1..100] OF POINTER TO VisuElemBase.VisuStructClientData; END_VAR VisuElemBase.g_ClientManager.BeginIteration(); pClientData := VisuElemBase.g_ClientManager.GetNextClient(); WHILE pClientData <> 0 DO pClientData[pClientData^.GlobalData.GlobalClientID] := pClientData; END_WHILE You have to make shure every no longer updated pointers in the array have to be deleted and no longer used by your code! Usage of this pointer access at your own risk :-) Works with SP16. From SP17 and newer there will be warnigs etc. using this solution as I remember. It will be great, if Codesys publishes a example or give a hint how to accesse this client values with the VisuUtil lib or other future-proof way!

Hello everyone. Raspberry Pi CM4 after some 1 week of work was hard reset mannualy several times and after these hard resets User Management file was missed (when click login button, enter login/password, error: User Management File missed). Also programm can not open file via SysFile library, but this file exists and size of him is 0 bytes, but must be more any way (I keep some kind of archive via this lib). What happens, how files corrupted? Where do I need try to find this error of the codesys or system whole? In the log files of codesys nothing interesting about this happens. Thanks for reading Is this enough hold PlcLogic and SysFileMap.cfg as reserve copy in another place for restoring the programm? And how automate restoring actions if programm files corrupted?

I thought it would be very easy to just connect to the ip address, but apparantly it is not. I am using WAGO PLC PFC200 and my PC as a webvisu. or else can you guys please advice me on which kind of camera should I use as a CCTV system in my project instead of IP Camera.

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
I ordered a cheap managed switch and tested it as soon as I received the switch. It works great! I even went a bit further. As you can see in the screenshot, I created 2 Codesys containers. Each one having 2 fieldbuses. The first one has EtherCAT and EtherNet/IP and the second one has EtherCAT and Modbus/TCP. All going through the same ethernet port from the PC to the switch. The switch splits it up into 4 different networks. The hardest part was to figure out how to configure the switch. @eschwellinger, thank you very much.

Post by opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

Post by davidbo on RPI can system operation like rm in a shell have an impact on a Task cycle time ^{CODESYS Forge talk (Post)}
I have noticed that a rm file1.txt command on a shell has an impact on the cycle time for a TASK writing to file2.txt. Seen in the Monitor fane of the Task configuration Furthermore if a TASK makes a system call like rm, its cycle time increases of course but it seems to have an invisible impact on other TASKs too. I have a TASK for handling communication over the CANbus (SPI) where it stops sending "Heartbeats" for many seconds when another TASK does a system rm. Why is that not seen on the Monitor fane? Is even codesyscontrol paused when system calls are made? The CPU load is about 30-40%

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
If you have a Windows system (RTE), then why not run the CODESYS HMI as separate controller. This could easily be moved to another PC if required. In the HMI you could also still use the Symbolic Var access as part of the Data Source Manager, although maybe OPC is the preferred way to make it more future proof. Or what about the Remote Target Visu. Then you can reduce the load of the main controller, while still only having to create one application including Visualization. This is now also supported for Linux systems. See: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_target_visu_for_linux.html https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_execute_remote_target_visu.html

Post by timvh on Visuutils FbOpenDialog(Extended) not open Dialog from POUs ^{CODESYS Forge talk (Post)}
I had a similar situation recently where this didn't work, but read to the end to see the solution. The reason is that CODESYS only downloads visualisations (dialogs) if they are part of the project or linked to the project. In your case the dialog is not loaded onto the controller. But the solution is pretty simple: Double click on the Visualization Manager in your application. Select the Tab "Visualizations". Here you can see that your dialog is not "checked". Do this manually and load your project on the controller. Then your code should be able to open the dialog, because now it exists on the controller.

Post by jacobwago on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello, I have experienced the same issue as described above but for the Modbus Serial configurator. Looking for a solution. In v3.5 SP19 Patch 7 the Modbus Serial Master Slave configurator has a "virtual" limit of 10 channels. In v3.5 SP18 Patch 5 this virtual limit does not exist. I can successfully copy back and forth from 18 to 19 with out any build error. However, this is not a good solution for our customers. What is even more confusing is that the IoDrvModbus library is the same version (4.3.0.0) for both SP18 and SP19. Please help in providing a fix to the virtual channel limit of 10 in SP19. Thanks,

Post by andrebrandt on FB string and naming ^{CODESYS Forge talk (Post)}
Hi Tim. Not quite correct. What i'd like, is when you place the FB in prog, i choose a block NTC10k, and name this RT401. What i'm trying to do, is to get the name RT401 automaticly into the FB, so i can put this into the string i pass in a struct. So in var in POU, i saw this a place i could do this, RT401: NTC10k(Tag:='RT401'), but i can't get this to work. I shurly must have had something like this in FB: FUNCTION_BLOCK NTC10k String TAG But it's here where I'm stuck...

Hello, by searching the forum, I have found an example of batch script that can be used to start codesys projct by temporarily setting env variables. However, I'm not sure how to modify this to start Codesys 3.5.20 and whether or not I need to specify "profile" with Codesys version at all. @echo off SET PROJECT=D:\TestScripts\Data\OnlineTest.project SET VARIABLES=POU.testint,POU.testoutput start /wait CoDeSys.exe --profile="CoDeSys V3.4 SP3" --noUI --runscript="D:\TestScripts\Forum_Environment.py" I have tried the following just to open the test project: SET PROJECT=C:\TEST\Example.project start CODESYS.exe --profile="CODESYS V3.5 SP20 Patch 2" But I'm not sure how to specify this project to be open after py script is executed. The py script should first add required library to the project and then project should be open.

Post by andrebrandt on FB string and naming ^{CODESYS Forge talk (Post)}
Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?

Power is connected to the pca9685 for motors of sufficient power or amperage. I tried to put another pca9685 but the same thing happens again. What is the possible problem?

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by siscu on Raspberry i2c master device ^{CODESYS Forge talk (Post)}
I want to implement an extended I2C master for Raspberry Pi Control. I was hoping for it to be as easy as creating a library with a FB that extends i2cMaster and associating it with a device following the forge drivers documentation, but I haven't managed to make it work as the driver behaves only as an i2c slave. I'm thinking this is because the forge forum only talks about extending i2c, and the master portion is omitted since most users won't want to add a custom one. I'd like to know if I'm doing something wrong. Is it really possible to make an I2C master extension device? If so, are there public examples we can check out? Any info on this topic will be appreciated.
