Redundancy tab
The Redundancy Tab displays redundancy-related information and allows redundancy
commands to be issued when the C300 FB is opened on the Monitor Tree in Control
Builder. The following table summarizes the parameter data you can monitor and/or
configure on the Redundancy tab of the configuration form for the selected C300 block.
See Redundancy parameters
also for further descriptions of these parameters.
Note that the Redundancy tab is exposed only when the Controller is configured as
redundant. The Module is redundant check box (MODISREDUN parameter) is checked
on the Main tab
of the C300 block.
