Debug communications between the SIDirect Communication Driver and the PLC

The OI Server Manager allows you use on-line diagnostics of the SIDirect Communication Driver components at run-time, locally and remotely.

Perform on-line diagnostics

• Select any active SIDirect Communication Driver on any node in the OI Server Manager.

  The Diagnostics branch is visible only if the Communication Driver is active as indicated by the green icon on the server branch. It contains the following sub-branches:

  • Client Groups

  • Structure

  • Transactions

  • Statistics

  • Messages

  • Device Groups

  Each of these sub-branches contains live information from the Communication Driver. They allow detailed diagnostics of objects within the SIDirect Communication Driver.

Note: If you have pokes that are folded, the diagnostics shows ALL items in the transaction. However, because they are folded, only items that have actually been sent have both the message ID and value. All other items that have not been sent, because of the folding, are listed in this transaction with the same timestamp but without the message and value.

For more information on Diagnostics, see "Using the Diagnostics Node" section in the Communication Drivers Pack help.
