Dear all

When I using PN/PN Coupler in PCS7 v9.0 with redundancy Station, I found it can not be configured on redundancy PN network.

But in PCS7 8.2, it ok when I installed HSP. But in PCS7 v9.0, I can not install HSP

The difference is Step7 v5.5 and v5.6, Siemens Germany can not fix this bug quickly.

Is there somebody can help me about this bug?

Siemens provided HSP 0244

HSP 0244 can be installed in PCS7 V8.2

But can not be installed in PCS7 V9.0

Nobody meet this issue?

PN/PN coupler is not applicable for PCS7 v9.0 redundancy System?

Hi JerryZh,

the PN/PN Coupler is not applicable for PCS7 V9.0 redundancy system.  And so Siemens locked that the PN/PN Coupler can configured on redundancy PN network.

The only thing I can imagine is that you make a project with V8.2 and configure there the PN/PN Coupler in the redundancy PN network and after that you immigrate that to V9.0.
But you have to remenber that this isn't tested and you have no grant.

Dear Heisenberg2

I tested config in v8.2, but when I use v9.0 open the project, in HW config notice early version installed, then the same issue as I install HSP in v9.0(can not installed success).

One more question, If I using v8.2 config HW and download, in v9.0 only programming, is it possible?

I'll test it later.

Dear JerryZh,

I tried to use the HW out of  V8.2 and the programm out V9.0 and with PLCSIM it's working. But I haven't got a real CPU, so I can't test this usecase.

 Dear JerryZh

You need a special fimware for PN/PN coupler to communicate with H-systems. Please contact your sales person in your country.
