[?]: DP/DP COUPLER not work

[obesound]

Hello, I have a problem with Dp/Dp coupler.
I followed the manual but I does not work.
All the leds in DP/DP coupler are ON.
Could you help me?
Thanks

There is only necessary to follow manual and to have correct hardware connection of cables. Please attach your project here in order to understand the problem.

Best regards,

did yu take the right GSD-file for the Coupler in both plcs?
How is it stripped.
How are the DIP configured.
Did yu use Diagnosebyte etc...

Yu have to pst more informations!

I have the same GSD file in both PLCs, the problem is that DP/DP Coupler have all leds ON.

X1 DP X2 DP
ps on on
dia off off

does the GSD MATCH with the coupler? there are different dp/dp copplers from Siemens.
take only the coppler to the Profibus and close both resistors (on PLC side and COPPLer)
Is the DP cable ok (No change of A and B)?
Is the coppler in the GSD configured like yur dip-Switches?

Hello

which coupler do you have ?

In the manual from the coupler v2 is there a fault in the example.

On page 6-12

DB10 Norm_Diag is the ARRAY [1..6] but it must be ARRAY [1..16]

Hello,

I think this problem from wrong configuration input and output word in Hardware config of
DP/DP coupler. Example, in master side you start by input word then output word that means
at slave side must start with output word then input word..
