Other possibly occuring statuses correspond to the PRIMARY_VALUE statuses. See 6.1.3 for details.
6.1.4 Integrator Blocks
The follwowing table lists the block errors documented by the Integrator Blocks:
Error Code Description Action
Out of Service Target mode is set
to ‘Out of Service
(OOS)’ If Automatic is the desired target mode, set MODE_BLK target
to ‘Automatic (Auto)’
