5.2 Determining Series 8 I/O block redundancy
Main tab checkbox invokes redundancy
The IOM blocks represent instances of the I/O Module hardware that reside on the I/O
Link network. There is a specific IOM block for each I/O Module type supported in
Experion.
The IOM block is used to:
configure the network address (the IOMNUM) of the IOM device.
If the IOM is configured to be redundant, you enter only one IOMNUM. In
either case, only one block is created which handles communication to and from
both physical IOMs.
The hardware design uses a set of push-in IOMNUM identifiers to reduce the
chance of duplicate IOMNUMs on the same link.
Each IOM block generates system events and alarms for soft failures, IOM
synchronization, and IOM switchover.
