9.0 Setpoints
The 680 indicator provides eight configurable setpoints for control of both indicator and external equipment functions. Setpoints
can be configured to perform actions or functions based on specified parameter conditions. Parameters associated with various
setpoint kinds can, for example, be configured to perform functions (print, tare, accumulate), to change the state of a digital
output controlling indicator or external equipment functions, or to make conditional decisions.
Weight-based setpoints are tripped by values specified in primary units only.
9.1 Batch and Continuous Setpoints
680 setpoints can be either continuous or batch.
Continuous setpoints are free-running; the indicator constantly monitors the condition of free-running setpoints at each A/D
update. The specified setpoint action or function is performed when the designated setpoint parameter conditions are met. A
digital output or function assigned to a free-running setpoint continuously changes state, becoming active or inactive, as
defined by the setpoint parameters.
Batch setpoints (BATCH = ON) which have digital outputs associated to them remain active until the setpoint condition is met.
The setpoint is then latched for the remainder of the batch sequence.
To use batch setpoints, set the batching (BATCHNG) parameter on the setpoints (SETPTS) menu. This parameter defines
whether a batch sequence is automatic or manual. AUTO sequences repeat continuously after receiving a single batch start
signal, while MANUAL sequences only run through once for each Batch Start signal. The batch start signal can be initiated by a
digital input (set to BATSTR), or an EDP command (BATSTART).
For a setpoint to be used as part of a batch sequence, its batch sequence (BATCH) parameter must be set to ON. If a setpoint
is defined and enabled, but its Batch Sequence parameter is set to OFF, the setpoint operates as a continuous setpoint even
during batch sequences.
In applications which contain both batch setpoint routines and continuous setpoints, it is good practice to keep
continuous setpoints separate from the batch sequence.
Do not assign them the same digital output.
Set the ACCESS parameter ON when creating and testing batch routines. Once the batching routine is complete and
ready for production, ACCESS can be set to OFF to prevent changes to the configured setpoint value, or to HIDE to
prevent changing or viewing the value.
Parameter Description Batch Continuous
OFF Off – Setpoint turned off/ignored
GROSS Gross Weight – Performs functions based on the gross weight; the target weight entered is
considered a positive gross weight
X X
NET Net Weight – Performs functions based on the net weight; the target weight entered is
considered a positive net weight value
X X
-GROSS Negative Gross Weight – Performs functions based on the gross weight; the target weight
entered is considered a negative gross weight
X X
-NET Negative Net Weight – Performs functions based on the net weight; the target weight entered is
considered a negative net weight value
X X
ACCUM Accumulate – Compares the value of the setpoint to the source scale accumulator; the
accumulator setpoint is satisfied when the value of the source scale accumulator meets the
value and conditions of the accumulator setpoint
X X
POSREL Positive Relative – Performs functions based on a specified value above a referenced setpoint,
using the same weight mode as the referenced setpoint
X X
NEGREL Negative Relative – Performs functions based on a specified value below a referenced setpoint,
using the same weight mode as the referenced setpoint
