2-182 Function MRR Landis & Staefa Division

This system-internal tag ("Reason for Reaction") denotes that the "reason" for a process

or maintenance reaction has not been set although a reaction entry exists.

The VISONIK DCS manages this "REAR" tag in the reaction programs, ensuring

optimum and fast reaction access. If this tag is not present, no process reactions will be

executed as a result of this "reason".

Errors of this kind are corrected automatically when the register is printed or when the

function VE (verify data file) is executed.
