I want to connect a m340 2020 cpu to two devices in 300m long. One with ethernet port and one with modbus port of m340. I want to know witch cable i must buy for modbus and ethernet??
Is cat6 cable good for both of them??
And another question, should i use 3 wire(D+,D-,0V) for modbus rtu or 2 (D+,D-)is enough??
