there are few problems i face 1) the address of cp in hwconfig is fixed(system default) and it can not change. 2)when i download the hwconfig of s7 400 station in cpu 412-2dp and s7 300 config in both s7 300 cpu and cp 342-5. Then when i run both cpus and cp342-5 after download the bus2f led of s7 400 start blinking and the sf led of cp and cpu314 doesnot blinking . when i disconnectt the profibus cable from cp 342-5 then also no sf led or bf led of s7300 cpu and sf led of cp342-5 blinks.. 3)what adress of cp is made when there is a default tick in s7300 cpu on (cycle/clock memory) update ob1 cycle image cyclicallye. please tell me what i do so these problems removed thanks i attach my s7 program please check its configuration are correct.

Hello basit, does your question still exists? Or did you found a solution? When the LED on the CP isn't blinking I think the configuration of the CP isn't compleated. Have you create a program with the FC DP-Send and DP-Recv within the S7-300 CPU? Sorry, I couldn't check your program cause at the moment I didn't got STEP 7 with me Please have a look at the following page. There you will find a detailed example for your configuration. PROFIBUS-DP Communication between two SIMATIC S7 Stations Good luck Sabine |
