Modbus Invalid CRC error
#4
I'm still strugling with a CRC error. I tried almost everything but without luck. So i was searching the internet for troubleshooting Modbus RTU issues and came across the below wiring diagram. So my question now is if it's needed to use a pull up and a pull down resistor like in the wiring diagram and could this might help to solve the CRC error?
