Using Batched Setpoints - Rice Lake IQ plus 800 Installation & Operation Manual

NOTE:
PAUSE, DELAY, WAIT SS,
COUNTER, and AUTOJOG do
not have the additional BATCH
parameter, since they are
always dedicated batch types.
On the other hand, the continu-
ous setpoint types COZ,
INMOTION, INRANGE,
–GROSS, –NET, BATCHPR,
TIMER, and CONCUR cannot
be used as batch steps.
Also, note that setpoints operate
independently from the display.
For example, the display may be
reading from the scale on
channel 1, while the setpoint is
reading from channel 2.

7-4 IQ plus 800/810 Installation Manual
The setpoints GROSSSP, NET SP, +REL SP, –REL SP, and %REL SP have
other parameters which give you even more control over continuous
setpoints. See Section 3, Configuration, for more information on each
parameter.

USING BATCHED SETPOINTS

Batched setpoints are active one at a time, in an ordered sequence. Since
there are 20 setpoints, the IQ plus 800/ 810 can control up to 20 separate
batch processing steps or operations. When a batch setpoint is active, the
corresponding digital output turns ON for the duration of the setpoint (batch
step). When the next setpoint in the sequence is active, it turns ON and the
previous one turns OFF.
To configure and use batched setpoints, you must activate a global param-
eter, called BATCHNG. This parameter defines whether a batch sequence is
automatic or manual. AUTO sequences repeat continuously, while
MANUAL sequences require a digital input signal (BATSTRT) before
restarting.

Also, you must connect two batching switches to two digital inputs. (See
Section 8, Optional Features, for information about the batching switches.)
These switches control two signals, called BATRUN and BATSTRT, which
allow a batch to run and start the batch. BATRUN is a normally-closed
switch while BATSTRT is a momentary normally-open switch.
When working with batched setpoints, remember that GROSSSP, NET SP,
+REL SP, –REL SP, and %REL SP can be either continuous or batched
setpoints. In addition to the global BATCHNG parameter, there is a separate
parameter for each batched setpoint, called BATCH, which you must turn
ON for batch processing. Otherwise, if BATCH is OFF and the setpoint is
enabled, it operates as a continuous setpoint (even during batch sequences).
