Dave Posted January 2, 2012 Report Share Posted January 2, 2012 I was wondering if anybody has some sample ladder logic for reading/writing data to two servo drives ( specifically SureServo model SVA-2100) using a V570 OPLC. The PLC will be the master and both drives will be slaves. I will be using discrete I/O to initiate moves and the Modbus will be used to preset various parameters( speed, position, accel/decel, etc.) I have not used Modbus before and would also appreciate any tips and recommendations regarding program structure and Modbus FB's. Thanks. Link to comment Share on other sites More sharing options...

You can see how to use Modbus FB for Servo Drive. One important point In this pdf, explanation is Turkish. But you can understand from images...
