Interface between SAP and OSI - PI

[Former Member]

Team,

Appreciate your response for a query from a customer. Find below

Kindly help us to get some more details from SAP about the connectivity between OSI-PI system and SAP (PP,EHSM and QM).

Because, we might use only for one way communication (pull) the data from OSI-PI to get plant information to update our SAP –ECC for informative
purpose of production reports and EHS.

Queries:

Plan A

1. 1.      Whether OSI-PI RLink is enough for the connectivity to SAP?
2. 2.      Whether any other interface other than SAP-PI or MII to connect OSI PI?

Plan B

    1.      From this year,  we are using Honeywell DCS (SCADA) system, whether Honeywell PHD system could connect SAP?

1. 2.      If the above answer yes , then what is the standard interface using for SAP and Honeywell PHD ?

   The above queries raised because of clarity required for OSI –PI interface minimal connectivity requirement.

Thanks and regards,

Irfan

Hi Ifran,

Recommend that you use PCo amd MII to integrate to ECC. MII has JCO and BAPI connectors for ECC as well as the capablilty to implement Listeners to receive IDOC from ECC. MII has additonal capabilities such as the Plant Information Catalog that will be very beneficial in defining historian data and providing business context around it.

PCo has a native OSP PI connector as well as MII connectors that can execute MII transactions directly; the transactions can then execute JCO and BAPI to ECC.

PCo can connect to Honeywell PHD using the PCo OPC HDA connector. (The Honeywell historian OPC server will need to be installed and activated, preferably on the PCo server.)  PCo also has connectors for TCP Socket, OPC DA, OPC UA, OPC AE, ODBC, OLEDB, FileMonitor, and additional native historian connectors (Aspentech IP21, GE Proficy, CiTectSCADA).

Irfan, Want to add one more scenario just in case,

If you want to pull data on demand from OSI-PI to ECC (Instead of push from MII to ECC), you can expose MII BLS as Webservice and consume that WS in ECC .

Thanks

Hi Irfan¡¡¡

Did you finally connect SAP PCo with Honeywell PHD Server using OPC HDA successfully?

I have read that it is possible to enable the OPC HDA Server in PHD and connect the PCo Client to read tags.

Did you find problems/issues in terms of firewalls, windows security, etc?

Thanks in advance

Hi Irfan,

You can use SAP PCo(Plant Connectivity), that can connect to OSISoft PI and ECC for a 2 way communication.

You can create a destination the corresponds to SAP ECC systems and an agent with Port type as SAP NW RFC Server.

Also, you can create OPC UA/DA/HDA type of agents to connect to OPC compliant shop floor systems like Scada, matrikon, etc.

Hope this helps.

Thanks,

Swaroop
