Micromaster 440 - Reading values

Dear all,

We are working with MM440 at th plant where i'm working. The MM440 is connected to S7 400 PLC. In the hw config the setting is 0PKW 6PZD and the addresses are 576...587. I know from the PLC program comment that the PIW576 is the ACM Status, PIW578 is the ACM Freq, the PIW580 is the ACM Current, ect. But what can i do if I don't know these information from the PLC program? How can I check that which value is on which port? How can i set the MM440 if i want to read the ACM torque values instead of ACM status on the PIW578 address? Please help me somebody! Thanks

Take a look at P2051- these are the send values to the S7400
so p2051.0= status word , 2051.1= frequency...etc
