Configuring the Discrete Batch Application
Inhibit Batch and Inhibit Totalizer processing
If the Inhibit Batch function is mapped to a discrete input:
•
When that discrete input is in the active state:
-
A batch cannot be started.
-
A Start Not Okay alarm is posted if starting a batch is attempted.
•
If the discrete input then becomes inactive, the batch does not start automatically.
•
If a batch is already running when the discrete output becomes active, the batch is not affected.
If the Inhibit Totalizer function is mapped to a discrete input:
•
The totalizer will not increment while the discrete input is active.
•
The totalizer will resume incrementing automatically when the discrete input becomes
inactive.
inactive.
•
If the discrete input is inactive, the totalizer is active, whether or not a batch is running. Even if
a batch is not running, the totals will be incremented if flow is detected.
a batch is not running, the totals will be incremented if flow is detected.
