How to achieve DP communication between the S7-200 and ABB 510 frequency converters in order to monitor the motor’s operating status (current, speed, alarms)?
Thread Content
The Knight S7-200 and the ABB 510 cannot use DP communication; they can only use Modbus communication. The hardware also relies on 485 communication. Set the ABB inverter to Modbus operation mode, and for the PLC side, write a MODBUS master program by using the Modbus library commands.
By installing a DP communication card on the upper side, communication can be established
I’m a beginner; I tried using DP communication but it didn’t work. So how should I configure it?
Communication cards need to be purchased on both sides; otherwise, only MODBUS communication is possible
