Communication Fatek PLC and Rexroth Drive

Hello friends.

Pliz help me with communication.
We have PLC Fatek FBs-20MC and Rexroth DKC02.3.

What message should I send to Rexroth to change parameter . For Example P-0-4030 (Jog Velocity).

I've tried to send:

BCD:01 (CR)
P-0-4030,7,w,15000 (CR)

Also I've tried

BCD:01 (CR)
A01:>P-0-4030,7,w,15000 (CR)

But there was no result, and parameter remained as it was before.

Hello. S still can't solve my problem. So I checked and understand that i'm sending message to rexroth but there are absolutely no answer from.

Maybe anybody knows and i need to change parameters to get the right communication between PLC and Rexroth DKC?
