Post by thysonfury on OPTO22 Groov Epic PR2 Modbus Comms Dropping out every 2 hours and 4 Mins ^{CODESYS Forge talk (Post)}
Hi after some assistance with an error on a Groov PR2 PLC. We have a few different communications set up as shown below: One Modbus TCP Slave Connection - ( Sending / Receiving Data from a PC ) Two Modbus TCP Master Connection - ( Reading Data from a UPS Panel and Reading Data Gas Chromatograph) One Modbus RTU Slave Connection 485 - (Reading Data from a fire and gas panel) One Modbus RTU Master Connection 485 - (Sending Data to a Telemetry Unit) All Licenses have been installed as per OPTO22 suggestions of the order below: Modbus TCP Master Modbus TCP Slave Modbus RTU Master Modbus RTU Slave When I check on License manager the RTU Master license seems to disappear on installing the RTU. (What ever reason I’ve been told this is “normal”). If I use Device License Read It will successfully read all the licenses correctly. Now the issue is every 2 hours and between 4. For what ever reason the communications seems to end and lock up for about 20 seconds. During this time even if I was logged into the PLC it would kick me off and I’d have to re type the password to enter. Most of the devices can handle this however the RTU flags up a communications failure at the SCADA and is raising alarms every 2 hours and 4 mins. We’ve had multiple people go through the code to check for anything obvious. Does anyone have any ideas?

Post by westcountryewe on ac_persistence not working when creating a Boot Application but works with a Direct Download to the PLC ^{CODESYS Forge talk (Post)}
I am using V3.5 SP18 Patch 5. I have noticed that when I Create a Boot Application from CODESYS, and upload this to my PLC via a USB stick the AC_Persistence does not work and none of my values that are in my PersistenceChannel are retained. However, if I connect direct to my PLC and I perform a direct download of my CODESYS program, my values that are in my PersistenceChannel are retained and work as they should. This makes me wonder if there are files that are missing when a Boot Application is created. I have tried taking a backup of my configuration files after performing a direct download, which gives me the plclog.zip folder, and appears to have the ac_persistence folder present within the file structure, however when I replace the plclogic.zip with the same folder that was created when I created a Boot Application, it still does not work but I wonder whether this is because the ac_persistence folder isn't stored in the correct location for reading. The .app and .crc files are embedded within the plclogic.zip folder, which obviously when uploading need to be standalone files in the root directory of the USB, so the intention there is clearly to extract the .app and .crc files and put them into the correct location within the USB. I wonder if it could be the same for the ac_persistence folder? I have tried moving it to different locations but none have worked. Has anybody else discovered a fix for this? I know the short-term solution is to do a direct download to the PLC but there are some logistical reasons why this isn't neccesarily the best solution for us.

Post by felipemsgarcia on Edge Gateway online, but PLC is not online ^{CODESYS Forge talk (Post)}
Hello, Up until yesterday (2023/11/20) I was able to connect to the PLC remotely with no issues through Edge Gateway. However, today I can see the Edge Gateway online but I can find the PLC even if I do a network scan. Following the same path as janber0206 @ https://forge.codesys.com/forge/talk/automation_server/thread/e78b11d7e9/, I looked into certificates and found that one of the Trusted publisher certificates has expired earlier today (2023/11/21). Please see image. Questions are: Does it affect the connection to the PLC through Edge Gateway? How do I fix it? Thank you very much in advance!

Post by hyys12 on CODESYS 3.5 dicovery of PLC modules ^{CODESYS Forge talk (Post)}
I have a WAGO PLC, to which I am establishing a connection. Here I use the autodiscover to register the connected modules. Now, I have tested the in-/outputs of the different modules, to verify they are consistent with how they are physically connected to the PLC in regards to how CODESYS has numbered them. Will CODESYS always number the modules closest to the PLC itself lowest, and the one furthest away, the highest? I am rather new to the program, so I both hope my question makes sense, as well as not being completely obvious. Thanks!

this is not supported - no config pages available for this. Why not just use the EIP on your NIC of the plc?
