Description

A peer cop health operation reads selected data from the peer cop communications health table and downloads the data to the specified %MW addresses in state RAM. To program an MBP_MSTR block to perform a clear remote statistics operation, use function code 9.

NOTE: Peer cop health is operational only when a peer cop-based I/O scanner has been configured.

The peer cop communications health table is 12 words long; MBP_MSTR indexes these words with the numbers 0 ... 11.
