Dear all,

sorry to dig out this old thread but it is better than remake a clone.

I have searched in lot of places (google and siemens forums) but I cannot find a good guide to do what I need:

I have a D425-2, TIA V13.1, with last HF, SSP, etc. I have profinet network with HMI, 17 G120Cs and one PLC 1214 F (safety PLC, yes).

The 1214, due to its versatility, handles the safety STO for Sinamics and also carries almost all the I/O data that the Simotion should read and write, so almost all signals are connected to 1214 and Simotion should "see them".

My confusion is this: I have used in the past, with EXTREME success the IO device, where basically under TIA I have set two exchange areas from two controllers (Simotion and 1500 F in that case), here  Icould do the same thing to transport the input and output handling from 1214 to Simotion but I have to write code that mirrors the data coming from prfinet to the physical output. And this is obviously not the very best.

I knew that the Shared device allows me to "automatically" makes that Simotion "sees" the periphery of 1214 as it was its OWN periphery, so I can handle directly the IO of the 1214 from D425-2.

Any1 can help me please ?

Danke in advance

Danke Meister.

In fact I was trying everywhere in TIA but nothing was helping me. So I will use the I-Device through Simotion und 1214-F where basically I send via profinet the input bytes and the Simotion is able to read them as "normal" peripheral.

One other question if possible, Chris.

I have an identical machine with same hardware and I would like to make them in communication .

I can choose Simotion "1" to Simotion "2" or

1214 "1" to 1214 "2".

Since shared device is not possible here and i Device is already used in the above mentioned manner, what would be the most smart way of making machines communicating ? I have to exchange some bits and eventually a couple of word, in total a space of 64 bits, not more.

The two projects are under TIA but are separate, not in same single project.

Danke again advance
