Plant dash board using MII with PCo link down

Hi Steve

I am working on a project "Plant dash board using MII" and also various other things integrated with SAP MII such as:

1. At the time of good entry vehicle weigh bridge & security cameras integrated with SAP.

2. Biometric attendance system integrated with SAP.

3. Shop floor machine PLC are integrated with SAP though OPC kepware to view real time status of shop floor.

My major concern is SAP PCo agent link goes down automatically down and both OPC and MII stops communicating with each other. I have checked the license it is perfectly fine and both m/c are pinging with each other. Please tell me what could be the possible reason.

    Hi Vivek,

    First, some questions:

    1. current version and patch of PCo and MII
    2. current version of Kepware
    3. is Kepware fully licensed?
    4. Are PCo and Kepware installed on the same server?
    5. Please detail the conditions and events around the statement "SAP PCo agent link goes down automatically".

    Regards, Steve

    Dear Mr setve,

    the error we are getting in the event log is " Error while establishing connection : Could not open UA TCP request channel"

    when the agents are down..

    same problem which vivek has mentioned.

    • Hi Vivek,

      I do not see any obvious issues with your configuration. In order to have this issue reviewed in more detail you will need to log a support ticket against MFG-PCO, and provide the documentation that you have provided here.
