Batch control methods
Batch control functions can be performed in three ways:
•
By using the function buttons on the transmitter display (see the Series 3000 transmitter
manual), or in the ProLink II
Run Batcher
window (see Section B.4)
•
By assigning a discrete input to a batch control function
•
By assigning a discrete event to a batch control function
If a discrete input or discrete event is assigned to a batch control function, the function is triggered
when the discrete input or discrete event is in an On state.
Table B-4 lists the batch control functions. To assign a discrete input or discrete event to trigger a
batch function:
1. Choose
ProLink > Configuration
and click the
Discrete Input
tab. See Figure B-3.
2. Select the batch function to be triggered. Batch functions are listed and defined in Table B-4.
3. Specify the method which will be used to trigger the batch function: Discrete Event 1–5 or
Discrete Input 1–2.
Note: You can assign one or more actions to a single discrete input or discrete event. All assigned
actions will be performed, as allowed by the configuration and current state of the discrete batch
application.
Example 2
Configure presets by percent of target under the following conditions:
•
The target is 200 kilograms
•
The primary valve opens at the start of the batch and closes when
180 kilograms have been delivered
•
The secondary valve opens when 100 kilograms have been
delivered
•
The end warning occurs when 160 kilograms have been delivered
0.90
Since 0.90 equals 90%, enter a close primary value of 90.
0.50
Since 0.50 equals 50%, enter an open secondary value of 50.
0.80
Since 0.80 equals 80%, enter an end warning value of 80.
