Differ model's PLC aim at Differ Profibus communications for both the CPUs . can select S7 connect or master/slave communications.
No Communication in same type of Models of S7-300 and PC
- Thread starter Utco
- Start date
I am not getting Both CPUs which address should be unique?
Because one CPU is giving the same error by LED BF1 and LED SF.
I can download program from second CPU through profibus on first PLC.
I can see program by Monitoring 1st PLC through 2nd PLC.
How to troubleshoot this Profibus Fault?
