Batch Operations

Batches are controled by digital inputs or EDP commands.
(BATRUN digital input) If a BATRUN digital input is configured, it must be active (low) for a batch to
Batch Run
be started, or for it to continue to run. If a batch is running and the input becomes inactive (high), it will
stop the batch at the current batch setpoint and turn off all associated digital outputs.
(BATSTR digital input or BATSTR EDP command) If the BATRUN digital input is active (low), or is
Batch Start
not assigned, batch start will start a batch, resume a paused batch or resume a stopped batch. If the
BATRUN digital input is inactive (high), batch start will reset the current batch.
(BATPAS digital input or BATPAUSE EDP command) The BATPAS digital input will pause an
Batch Pause
active batch, turning off all associated digital outputs EXCEPT those associated with CONCUR
and TIMER setpoints, while the input is active (low). As soon as the BATPAS digital input is made
inactive (high), the batch will resume.
BATPAUSE EDP command works the same, except the batch will not resume until until a batch
start signal is recieved.
(BATSTP digital input or BATSTOP EDP command) Stops an active batch at the current setpoint and
Batch Stop
turns off all associated digital outputs.
(BATRST digital input or BATRESET EDP command) Stops and resets an active batch to the
Batch Reset
beginning of the process.
To prevent personal injury and equipment damage, software-based interrupts must always be supplemented
WARNING
by emergency stop switches and other safety devices necessary for the application.
Batching Switch
The batching switch option, PN 19369, comes as a complete unit in an FRP enclosure, with legend plate, locking
stop switch (mushroom button), and a run/start/abort 3-way switch.
Both switches are wired into the indicator's digital I/O terminal strip as shown in Figure 8-1. Each switch uses a
separate digital input. Digital input #1 must be set to
Once cables and switches have been connected to the indicator, use the setup switch to place the indicator in setup
mode. Use the DIG I/O menu (see Section 3.2.12 on page 47) to configure digital input and output functions.
