Hi there,

Im having difficulties, controlling ATV 320 vsds over Modbus SERIAL RTU with ioscanner from a M221 with so machine basic,

Iv followed all literature I could Find but to no avail can I get any communication, Im trying to use the Pre made functional drive blocks,

Im pretty sure my connections are all correct with the necessary end of lines on the RS485 side of things, and the drives are addressed correctly with correct baud rate etc and their commands set to be received on modbus

Can any body see what im doing incorrectly?

Cheers Tom
