Read/write OPC DA server with SAP

Dear Experts,

I would like to read and write "tags" (data) from a OPC DA server via SAP EWM.

I have not work with this kind of connection before.

I am analyzing the options below but before I start I would like you to advise me:

1) SAP ODA with "SAP ODA connector"

2) PCo(Plant Connectivity)

3) PCo(Plant Connectivity) with "SAP ODA connector"

4) Others

Which would be the best option?

Thank you in advance

Sincerely, Iban Ariz

Is it necessary SAP Gateway in all the cases?

You could certainly use SAP MII as well. It is optimized for these types of use cases.

Thanks Rick.
We would like to control a PLC(Programmable Logic Controller) and its movements via EWM.

I am analyzing the different PCo agents: OPC DA and Socket

The first one(POC DA) requires an OPC server to connect the PLC.

The second(socket) one seems to be direct connection with PLC.
