Seeking information on PCO

[Former Member]

We are about to start using PCO because we hear it can do a lot of things that MII and the UDS cannot do. I have a few questions and I appreciate any feedback I can get on the subject.

Most of the information I can find on PCO is on the installation or on the SDK. Is there any documentation on its general use and how we integrate it with the BLS?

What datatypes are accepted and allowed to trigger PCO event handlers?

Is PCO used similarly to the UDS where you set up your event handlers and in the BLS you simply call the event handler session by using an action block or do we use PCO in a sense that we create one or many instances of PCO where we can start and stop each session?

any nformation or documentation would be extremely helpful and I apprecia

PCo Agent Instance Notifications are the Event Handlers. You can configure and use as many notifications as you need. A Notification can call an MII Transaction an pass a Notification Message (XML) to a Transaction variable that contains the data that Notification has collected that the Transaction needs to process.

Since PCo can do the Event monitoring from a variety of sources (OPC, Socket, others can be added with the PCO SDK) you do not need to schedule MII Transactions to query data from PCo to determine if there is work to do, PCo can call the Transaction directly and send it the data to process at the same time.

PCo 2.1 also includes an OLEDB agent that can be queried from MII as well. This agent does not support Notifications, however.
