Hello, I am using a raspberry pi cm 4 with codesys and have had success for the most part, but recently have been getting an error when trying to login and connect to the raspberry pi. The error reads "invalid result package" and is shown in an attachment below. This error will then not allow me to log on. I have tried previous versions of the same project and have had these issues as well. The project had been working perfectly for a while before this and I cannot figure out what has caused this...
Hi, I have seen this problem many times throughout the forum but none of the solutions have helped. I am using raspberry PI CM4 with debian buster as the OS. I am to trying to connect to separate IO modules through RS485 communication. I have attached a screenshot below, everything has been working in the past, but is not working the moment so I am curious to what might have changed. The modules are being called correctly through modbus and then set in the config file as Linux.DeviceFile.2=/dev/ttyAMA3,...
The installed OS is Debian and using 4.4.0.0
When trying to communicate with RaspberryPi through Codesys I keep getting the error "no device is responding to the scan request". I have looked at other forums and tried the solutions posted there with no success. Is there any other possible solutions?
