Post by fred on Rasperry Control Debian 12 ^{CODESYS Forge talk (Post)}
Hi, I have Proxmox running on a Rasperry 4 and have debian 12 ARM installed here. I wanted to install Codesys Control for Raspberry on it. According to the messages, the runtime environment and the gateway were installed successfully, but I can't find a device to downplay a program. The sudo service codesys start command fails. (see image) Does somebody has any idea? Thank you for your help! Greetings Fred

Post by aconley on Static Code Analysis ^{CODESYS Forge talk (Post)}
I'm using CODESYS 3.5 SP16 Patch 6. I would like to incorporate static code analysis as part of our CI/CD pipeline. 1. Is there a way to execute the static code check from the command line or python script? 2. If you can't do it from the command line, is there a way to export the results from the application?

Post by lorenzo-pisoni on SysProcessExecuteCommand ^{CODESYS Forge talk (Post)}
Hello, I'm encountering an issue with the Sysprocess library while attempting to execute commands to transfer a file from a NAS to my PLC. Currently, I'm trying to test a simple "reboot" command, but it doesn't work as demonstrated in this video: https://youtu.be/77c7Af5xRhE?si=uFZdB6fTNQitzWMQ. I'm using CODESYS V3.5 SP18 Patch 4 (3.5.18.40). From other sources, I've learned that to enable the PLC to execute commands, I need to add the following line to the file CODESYSControl_User.txt: [SysProcess] Command=AllowAll However, the issue I'm facing is that this file doesn't exist on my CPU. I have full SSH access and can see all files, but only CODESYSControl.txt is present. Adding the command to CODESYSControl.txt hasn't resolved the problem.

Post by tomast on Codesys and Siemens SINAMICS 20 modbus RTU "Response CRC Fail" ^{CODESYS Forge talk (Post)}
Hi everyone, I'm currently working on a project involving the control of 5 VFDs via Modbus RTU, this time using the WAGO 750-8212 CPU. So far, I've managed to make progress, but I've encountered an issue. While I can successfully read and write to all the registers I need, I consistently encounter a "Response CRC Fail" error when attempting to write the value 1151 to the STW register at address 40100. I'm able to set the frequency via register 40101 and adjust all other parameters using different registers. Setting STW to 1150 results in the drive ready boolean from the ZSW-bit being received instantly. However, the moment I attempt to send 1151 to register 40100, I immediately receive the "Response CRC Fail" error for all channels. I've also attempted to use combined control, employing Modbus for frequency control and starting from a digital input. Everything seems to function properly until I send the start command to the VFD. Interestingly, I consistently encounter the same error the moment I send the start command, regardless of whether I use register 40006 (high) or 40100 (1151). Could someone please assist me in resolving this issue?

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

Hi,is there any canopen library where is implemented sdo write with unspecified datalength (command byte 0x22)? I tried caa cia405 canopen library but it doesnt support this, but my slave device accept only 0x22. Thank you for any help.
