Post by atone on CAA File Handling: "Read only" error ^{CODESYS Forge talk (Post)}
In case of error while opening the file to read you assume that the file doesn't exist and try to create one. But it could be that the SD card is not ready yet or simply not there. I would try to check first if the SD card is there and accessible. Otherwise with FILE.Create you could end up creating a new directory that is not mapped to the SD card. This would explain the errors even after a reboot, though it doesn't explain the READ_ONLY_CAA error I guess? I would use FILE.DirOpen and FILE.DirList to check if the SD card is there and ready.

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.
