Possible values are:
AVAILABLE - Redundancy is configured and enabled. When
it is available, the system switches buses when
communications with an active block is lost. You are not
allowed to switch single blocks between the buses.
NOT AVAILABLE - Redundancy is configured, but not
enabled (for the AC 460, one of the CI560 TRIO MIB
submodules is either MISSING, FAILED, or READY).
NOT CONFIGURED - Redundancy is not configured on the
REMOTEIO templet.
Enabled or Disabled. Use this field to enable or disable diagnostic
checking for all blocks on the Field Bus.
Use the context menu associated with the Bus A or Bus B status
and select the appropriate command to do the following:
Select Activate All to activate all inactive blocks on the bus (either
bus for the AC 460). This is equivalent to all blocks signing into
CCF. When a block is not active, CCF channels related to it are
given a BAD data quality. This does not change any configuration
parameters of the block. If a block was made inactive via its TRIO
Block Display, this command can be used to activate it.
Select Redundancy and from the submenu select:
• Establish, Terminate, or Switch Bus (see
the SC Controller
• Activate Bus, Deactivate Bus, Restart Bus or Switch Bus
(see Redundancy on the AC Controller
Select Diagnostics and from the submenu
select:
•Enable,
•Disable or
•Clear All (to clear all diagnostics for every
block on the bus)
