Configuring the Discrete Batch Application

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
manual), or in the ProLink II
Batcher Control
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.
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:
batch function:
1. Open the ProLink II
Configuration
window and click on the
Discrete Input Mapping
tab.
The panel shown in Figure B-3 is displayed.
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
180 kilograms have been delivered
•
The secondary valve opens when 100 kilograms have been
delivered
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.
