HHHHHHEEEEELLLLLPPPPPP!!!
Calling on all magicians please help me,
Im busy setting up communication between 2 S7-315-2DP on Profibus DP.
I have configured one of the CPU's as a Master Module and the other as A slave ...I have set up the Data configuration from within the Slave station in the Masters Hardware configuration to set up Data leghts and Start Adresses...
I used SFC14(DP_Read) and SFC15(DP_Write) to Read and Write the Data to and from the Slave but it does not recognize the DP Slave Start Adress...I get error 8090h
Has anyone done this and can assist me ...what am i doing wrong...
