Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Hi, everyone! I'm trying to set up a PLC controller and a connection to an EtherCAT slave device in Codesys. I want to create a flexible program that I can upload to multiple controllers with different remote IO connected (same program). On one plant i may have 5 AI-cards and 3 DO-cards, and on another I may have 4 AI-cards and 2 DO-cards. For not needing to maintain several different programs wih different devices defined in the program (one for each set up) I thought that using a remote IO would make it easier having a single program. That way I could refer to different memory addresses instead of predefined slots/channels and IO's, that would give me errors if there was a different IO on the plant than what the program expected. When I tried setting up the etherCAT master, I saw that I had to define the etherCAT slave devices with the different IO'cards for me to be able to refer to the memory addresses in a PRG. Exactly what I was trying to avoid. My setup is something like a program that can handle 16 separate pump controls. In a year maybe 6 plans get deployed, and depending on how large the project is, the number of pumps can vary between 4 and 16. And the managers dont want to have IO's for all 16 pumps on every cabinet, and I dont want to maintain 16 separate projects files in case of updates etc. I thought the best way to tackle this was having a single project that read/write data to the different pump IO's by remote IO (fieldbus ethercat) addresses. And the number of pump controls are activated by an external GUI. If pump 1-6 is activated by the GUI, then the PLC-program tries to read/write input/outputs from predefined addresses for the expected IO's. My test setup is a PFC200 WAGO controller and a EtherCAT fieldbus coupler (750-354) with some IO. I hope I didn't explain this too horrible, and if there is a more easy and elegant solution for this challenge I appreciate a feedback on this.

Hi, eschwellinger, I have the same problem, but I can not resolve the problem following this forum. There are my situation: pi@RevPiXXXX:~ $ uname -a Linux RevPiXXXX 5.10.120-rt70-v7l #1 SMP PREEMPT_RT Thu, 28 Jul 2022 10:36:48 +0200 armv7l GNU/Linux After "top": It looks like runtime is not running. One more piece of information to refer to, when I reboot the device it is possible to scan the device. Looking forward your reply.

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

Post by timvh on JSON ^{CODESYS Forge talk (Post)}
I don't know the details of jsonArrayWriter, but the common behaviour for an xExecute input is that the FB starts on the trigger that it gets TRUE. In your case xExecute is never FALSE, so it is never triggered again to start the jsonArrayWriter. So change the condition from TRUE to a variable which you set to TRUE with the "xFirst". Then when the jsonArrayWriter is done (xDone), or has an error (xError), then set this variable to FALSE.

Post by umair on Code for reading 4 address to get 1 value of sensor (Ethernet IP) ^{CODESYS Forge talk (Post)}
Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Hello. I'm trying to use RecipeManCommands.ReloadRecipes Method for getting recipes from files. When I call the method it does not generate any error but also not reload any recipe to the recipe definition. Actually I have 6 recipe files on the directory PlcLogic. The rest of the methods work creating recipes, saving to file, etc. Does any one have the same issue? it is something to be set on the recipe manager?

Post by ph0010421 on General question about library versions ^{CODESYS Forge talk (Post)}
Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks

Hi, it is enough to copy the files to /home/codesys/PlcLogic/Application and adding the lines [CmpApp] Application.1=Application to the eRUNTIME.cfg, if your Application in your program is also called "Application". Reboot -> Bootapp should be loaded. If not please check the log /var/log/runtime.log There should be a line which explains why the bootproject is not loaded.

Hi, Recently I bought a CR710S controller from IFM. I installed Codesys V3.5 SP11 as recommended and all required packages (including the safety packages and the IOWrapper package). However, I can't even open the project template without getting errors related to libraries failing to load (below in the first print screen). Then, clicking ok appears only 2 errors (second print) and when trying to go to simulation and login I get another 2 different errors (third print). I really appreciate any help anyone can provide, I'm completely stuck on this right now.

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
https://forge.codesys.com/forge/talk/Engineering/thread/92c913bf7c/ Solved by changing the ethercat master version after reading the thread linked above. I think I need to read up on why this happened. I understand that placeholders should point to a particular version for obvious reasons however what has occurred in this instance is different. The example project was released as a "project archive" but it seems to load differently based on what I've got installed in my repositories. I'm going to dig into that tomorrow but any advice is welcome.

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
I have a Raspberry Pi 4 we have been using for years to run CODESYS for development purposes. I recently have had to re-install the OS (Raspberry OS lite). The only change to the default configuration is not creating the "pi" user during install. I (apparently successfully) installed the 4.10.0.0 control on the Raspberry Pi. We have licences on a dongle. I am able to start the control. systemctl status shows it as running for a little while (exactly, precisely 30 seconds as per my tests, every time), then it becomes exited. I can restart the control, and the same thing happens again. Every time. In the brief moments it is running, I can log in to the PLC. Working fast and restarting the control many times, I have been able to configure users. I have been able to download my application. I have been able to run the application, and stop on a breakpoint. I have been able to connect with the licence manager and confirm the dongle is detected and licences are listed as OK. I see nothing wrong until the service just exits. I have found nothing in the logs. It is like the runtime just terminates with no error code or message after exactly 30 seconds. Any help would be appreciated.
