Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi Dear All, I'm using my raspberry PI4 as a CoDeSyS PLC (Build from scratch with custom electronics). I was able to implement all fieldbuses with the exception of Modbus Serial. I'm using the internal Port (GPIO) and I configured it in /etc/Codesyscontrol_user.cfg the following away: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 Linux.Devicefile.2=/dev/ttyS0 I'm using COM2 on Master configuration. I'm using a interface board from TTL/RS485 (bidirectional board), and it's works perfectly with other devices but not in CoDeSyS. I'm able to send data with python script and read it on my pc using putty, but when I use a modbus slave simulator to interface with codesys I always get red icons on master and slave. (Please find image attached). I'm pretty shure that this might be a bad parameter on my CoDeSyS runtime configurstion file. Can someone help me? I'm stuck and this is for my master degree certification.

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 laazik2 on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
I am actually wondering as well if there are plans to fix it or not? As adding two modbus devices creates it's own problems with connection limits and other issues, which some slave devices have.

Hallo, gibt es eine Möglichkeit die Modbus Slaves (ModbusSlaveComPort) innerhalb der Applikation über ein Variable zu aktivieren oder zu deaktivieren? Bilder als Datei Danke!
