Setpoints
The IQ plus 710 indicator provides eight programmable setpoints for control of both indicator and external
equipment functions. Setpoints are configured to trip based on specified conditions; tripping the setpoint can be
used to request indicator functions (print, tare, accumulate) or to change the state of a digital output controlling
external equipment.
Figure 8-1 shows the general structure of the SETPNTS menu. See Section 3.2.7 on page 27 for a detailed
description of the SETPNTS menu. The eight setpoint kinds are described in Table 8-1 on page 52.

Batch and Continuous Setpoints
IQ plus 710 setpoints can be either continuous or
batch setpoints.
Continuous setpoints
are free-running: the indicator
constantly checks the input channel for the setpoint
value at each A/D update. If the input channel weight
reading matches the setpoint value, the indicator sets
the corresponding digital output on.
Batch setpoints
are active one at a time, in an ordered
sequence. The IQ plus 710 can use batch setpoints to
control up to eight separate batch processing steps. A
digital output associated with a batch setpoint is on
until the setpoint condition is met, then latched for the
remainder of the batch sequence.
To use batch setpoints, you must activate the
BATCHNG parameter on the SETPNTS menu. This
parameter defines whether a batch sequence is
automatic or manual. AUTO sequences repeat
continuously, while MANUAL sequences require a
BAT S T RT d i g i t a l i n p u t o r S T RT BAT m a c r o
command before restarting. As shown in Table 8-1 on
page 52, GROSSSP, NETSP, and –RELSP setpoint
kinds can be configured as either batch or continuous
setpoints.
The BATCH parameter must also be set on for each
batch setpoint. If the setpoint is defined but the
BATCH parameter is off, the setpoint operates as a
continuous setpoint, even during batch sequences.
