hi Sohail

I have the solution of this because just now i am successfully communicate S7-400 to micromaster 440. pls follow above thing.

in Hardware Configuration ,
select Profibus DP -> Simovert->Micromaster 4->and Select ->4PKW, 8WORD CONS.

then in first slot u will find4 input and4 output word, that are important.

then in logic configure like above, u need to use DPread and write block for interacting with Drive parameter.


// Process data exchange

// Control word 1 + main setpoint to MM440
CALL "DPWR_DAT"
LADDR :=W#16#3EC ------This isyourfirst starting addressof INPUT which u have convert in HEX
RECORD :=P#DB1.DBX8.0 BYTE 16 -------DB ADDRESS WHERE U CAN RECORD
RET_VAL:=MW802

// Read 8 word of process data
CALL "DPRD_DAT"
LADDR :=W#16#3EC-----This isyourfirst starting addressof OUTPUT which u have convert in HEX
RET_VAL:=MW804
RECORD :=P#DB1.DBX24.0 BYTE 16-------DB ADDRESS WHERE U CAN RECORD

in Drive parameter u have to set some parameter.

p700 = 6 ----------- Command ( Start, stop........etc---- which is actually configure Control word r0054)
p1000 = 6 -------- Complite control from Profibus.
p2051 (0)= 52 --------------- Reading the status of the drive (Running, Fault ........etc--staus word r0052)

r0054 and r0052 are drive read parameter. but r0054 is the cotrol word so u can control of this bitby changing in it by profibus communication.

Pls try this, because i am communicating14 drive with this all configuration.

Thakns and Regards
