Setpoints 51
CONCUR Allows a digital output to remain active over a specified portion of the batch
sequence. Two types of concur setpoints can be configured:
Type 1 (VALUE=0):
The digital output associated with this setpoint becomes
active when the START setpoint becomes the current batch step and remains
active until the END setpoint becomes the current batch step.
Type 2 (VALUE > 0):
If a non-zero value is specified for the VALUE parameter, that
value represents the timer, in tenths of a second, for this setpoint. The digital
output associated with this setpoint becomes active when the START setpoint
becomes the current batch step and remains active until the timer expires.
NOTE: If more than one concurrent setpoint is configured, each must be
assigned to a different digital output.
Ö
DIGIN Digital input setpoint. Requires a specific group of digital inputs to be in low (0
VDC) state to satisfy the setpoint. The digital output associated with this
setpoint is held in a low (0 VDC) state until the inputs selected for the digital
input mask are all in a low state.
Ö Ö
AVG Average setpoint. Performs functions based on the calculated average weight
over a specified number of A/D samples.
Note that this setpoint is based on the raw A/D weight value, rather than the
rounded value shown on the indicator display. For example, if the display shows
50.0 but the actual raw A/D value is 49.99, the setpoint will not be satisfied.
Ö Ö
TOD Time of day setpoint. Performs functions when the internal clock time of the
indicator matches the specified setpoint time.
Ö Ö
DELTA Delta weight setpoint. Satisfied when the change in weight on the scale is equal
to or exceeds the absolute value specified for the setpoint.
Ö
CHKWEI Checkweigher setpoint. Allows specification of over- and under-weight values.
Up to three digital outputs can be configured to represent overweight,
underweight, and accept conditions.
Ö
PLSCNT Pulse counter setpoint. Performs functions based on pulse counts received by
a pulse input card.
Ö
PLSRAT Pulse rate setpoint. Performs functions based on the pulse rate received by a
pulse input card.
Ö
ALWAYS Always setpoint. This setpoint is always satisfied. It is typically used to provide
an endpoint for true/false branching batch routines.
Ö
NEVER Never setpoint. This setpoint is never satisfied. It is used to branch to a
designated setpoint in true/false branching batch routines in which the batch
will not continue through the normal sequence of batch setpoints.
