DP/DP Coupler configuration problem

hi friends

I was try to connect dp/dp coupler in S7-300 cpu , HW cong are add in TIA V15 but i got some error on communication . i attache some picture below . how to solve that.

Hello mpvel;

What error messages do you receive when you configure your DP/DP coupler?

What are the contents of the diagnostic buffer that you can link to this DP/DP coupler?

Has the coupler.s second slave interface been configured on a separate Profibus-DP master?

Dis you setup the data exchange areas so they are the opposite (same data size, inputs for the first master become outputs on the second master) in the 2 masters individual Profibus configuration?

What are the special features of input/output addressing with the DP/DP coupler?

 Sir,

    i was getting error in coupler SF1 , SF2 led on condition and BF1, BF2 led flash conditionin software we got in error HW not found in tiav15

in our configuration between s7 - 300 data exchange between DCS both device are master our coupler act like slave .

hi mpvel,

How did you config your coupler?

As per the LEDs both sides are not available on Profibus.

Which Profibus addresse did you assign in HW-config? Did you assign addresses on coupler with dip-switches? when you change the addresses, the coupler needs a restart to adopt the new parameters.

Have you had a look in the manual?

Dear mpvel,

Can you please tell us how you solved it? I'm experiencing the exact same issue.

Addressing seems to be fine, restarted the coupler but no result.

Thanks!

Hello Bram;

"Addressing seems to be fine..." ?

Do you have any active LEDs on the DP/DP coupler or on the CPUs of your project?

Could you show us the configuration of both sides of the coupler (from the different projects you are using it in)?

We might be able to help you examine them and maybe discover the source of the problem.

Hope this helps,
