KK120of MDVC in SINAMICS S120

Dear Sir,

Presently at one of our client we are replacing the master drives with sinamics drives.We are replacing master drives[CUVC] with CU320-2DP and PM240. Here we are facing problem in program conversion in one application. In this application Drive is sending parameter KK120(Pos Angle of Encoder), based on this parameter plc is doing some calculation, and after a set position is reached PLC send a bit to reset the encoder position, here they are moving 0.000% and 0.001% values on parameter P172 through KK526(switch) the switch setting is done by U176=B3201. Now we don't want to disturb the PLC program but we are unable to find parameters OF position angle(KK120) and reset position(P127) i sinamics Drives. Please guide us which parameters or logic we need to make in S120 CU to achieve above functionality Pl find the attached master drive program for your reference
