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.

Assignment options ON state actions
End discrete
batch None Specify the method that will
be used to perform the batch
control function:
• None
• Discrete input 1
• Discrete input 2
• Discrete event 1
• Discrete event 2
• Discrete event 3
• Discrete event 4
• Discrete event 5
• Ends the batch.
• The batch cannot be resumed.
• The batch totalizer must be reset for the next
batch.
Inhibit discrete
batch • Batch cannot be started.
• Inhibit batch is used for temporary lockout.
Inhibit discrete
batch totalizer • Delivers the batch but does not totalize.
• Inhibit totalizer is used when process fluid is
recirculated.
Inhibit discrete
batch flow • Delivers the batch but does not report flow rate.
• Inhibit flow is used when the flow cannot be
stopped, so that only the flow actually dispensed
is counted toward the batch.
Reset discrete
batch • Resets batch total to zero.
• Batch reset cannot be performed while a batch is
running or while a batch is stopped. Before a
batch can be reset, the batch target must be
reached or the batch must be ended.
• The batch controller can be configured to reset
automatically on start. To configure Reset on
start, see Section B.3.2.
Resume
discrete batch • Resumes a batch that has been stopped.
• Counting resumes from the total at which the
batch was stopped.
Start discrete
batch Starts the batch by opening the flow control valve(s)
and/or starting the pump.
Stop discrete
batch • Stops the batch.
• The batch can be resumed if the batch total is
less than the batch target.
• If lockout target is disabled as a control option, the
operator can change the target before resuming.
• To enable or disable lockout target, see
Section B.3.2.
Increment
current batch
preset Selects next configured preset (as listed in the
preset menus) for use in the next batch.
Print screen The configured screen is sent to the printer (e.g.,
batch total).
