BRCV-Configuration in WinCC OA for a TSPP-Connection with a S7-1500

[Eric Schrön]

Hi Forum,

we configured a TSPP-connection between WinCC OA and S7-1500. For this issue we need the BSEND and BRCV blocks in the TIA Portal. But the TIA Portal also wants the item R_ID for the parametrization of the BSEND block. The parameter R_ID has to configured at the partner side of the S7, at the WinCC OA. Is this right and where can I do this?

Thanx for responsing

At the S7 TSPP connection config you can define the 'CPId', 'PC-Rack', 'PC-Slot' and 'PCId', which must match the configuration in the S7 PLC.

Thanx for reply! We found these settings! But in the TIA portal the BSEND block wants an item, which we don't know how parametrize! In the TIA portal tutorial is explained, that this setting must be equal with an setting from the partner? Because we don't have this setting, we don't what to paramtrize???

I guess you can leave the 'R_ID' zero, because you do not need to pair a BRCV with a BSEND.

We tried already with zero, but it doesn't worked!

For TSPP you only need a BSEND. To my knowledge WinCC OA does not send any response back.
