Run

The Run bit is an optional status value that can be generated and used within the control system to keep track of the status of a particular unit. Generally, the Run status bit is set when any of the phase blocks associated with the unit start and everything in the phase blocks is processing normally. When the Run status control relay is enabled, none of the remaining unit status bits should be set.

This status bit is used only within the control system program and is not monitored by the batch control system.
