Profibus

[GERRYJJERESANO]

Hello,

My situation is, our plc which is CJ2m and have a module of cj1w-prt21 will be connected via profibus with siemens S7-300,.

Master s7300 - Slave Cj2m with prt21, Station 7, with mach.no.4 and unit number 7.

Any ideas why we cannot establish proper connection. But the BF led blink in prt21.

Thanks in advance,
