Control Signals

Using the default TagMap file, all control signals are sent by AVEVA Batch Management with Foxboro DCS components directly to II0007 of the corresponding phase block. The PHASE_EXEC sequence block (located immediately following the unit block in every compound) then performs the required control operations on the particular sequence block.

# UNIT STATUS TAG EXTENSIONS (Discrete)

Equipment system tag extensions correspond to batch information that is downloaded to unit blocks when the corresponding unit is allocated to any batch. All items are downloaded from AVEVA Batch Management with Foxboro DCS components to the corresponding unit blocks, except for STATUS, which is read (checked) by AVEVA Batch Management with Foxboro DCS components for an acceptable status value before AVEVA Batch Management with Foxboro DCS components allocates the corresponding unit.

Note: When Batch Manager is started, AVEVA Batch Management with Foxboro DCS components downloads the STATUS word with the model default status value (Batch Manager Environment parameter). With this parameter enabled, sequence logic code should continually update the STATUS word to ensure the value does not represent an undesirable status.

The unit control tag extensions correspond to batch HOLD, RESTART, and ABORT control signals that are sent by AVEVA Batch Management with Foxboro DCS components to the corresponding unit blocks. As a default configuration, the PHASE_EXEC block is configured to process these signals.

CAMPAIGN_ID and LOT_ID are not included as defaults to conserve string allocations; however, they can be reconfigured for inclusion. All unit control tag extensions must be included in the II000n word (the default is II0007) for compatibility with PHASE_EXEC functionality.
