Good day! We have two CPUs in our plant. i.e. CPU 417-4H (6ES7 417-4HL04-0AB0) and s7-200 ( 6AG1214-1BD23-2XB0). Y-coupler (153-2BA02-0XB0) with two IM153-2 (153-2BA02-0XB0) and EM277 Profibus DP (6AG1277-0AA22-2XA0) . Please find attached picture for overview. Now the challenge for me is to send and receive data between two PLC. s7200 V memory address starts from V0.0 till V28.7. inputs V0.0 to V3.7 - type bool inputs VD4,VD8,VD12,VD16 - type Real outputs VD20, VD24 - type real inputs v28.0 to v28.7 - type bool I have assigned addresses in DB100 (picture attached) according to data type of V memory. Using FC100 (picture attached) I am loading inputs from PIW/PID and transfering it to respective DB addresses. similarly in case of outputs from s7200 I am loading respective DB addresses and transfer data to respective PQD. I am doing this practice for all above mentioned V memory addresses. Now the holding point is I am not getting any values in my DB100 ,I cant see any data in FC100 as well while in monitoring. I have uploaded pictures and test project backup in zip format. I would really appreciate your support in subject problem.Thanks

Hello jawadbaig; Please make sure that you have followed step-by-step the following FAQ, to establish Profibus-DP exchanges between your S7 CPU and the EM 277. Pay special attention to point 7, showing how you configure the V-data memory in the S7-200. How can you communicate data between the S7-200 and the S7-300 via PROFIBUS DP? Unfortunately your earlier zip does not show this particular configuration, and it is crucial. Hope this helps, Daniel Chartier |
