4 SETPOINT PROGRAMMING
a) FUNCTION
Once the Digital Counter function is chosen for one of the assignable digital inputs, the setpoint messages
shown here will follow the assignment message. Each closure of the switch will be counted, by either adding or
decrementing the counter value. An alarm may be configured when a certain count is reached. The counter
value may be viewed in A4 MAINTENANCE\GENERAL COUNTERS\DIGITAL COUNTER.
To initialize the counter, program the counter value here and then change S1 469 SETUP\CLEAR DATA\PRESET
DIGITAL COUNTER to "Yes".
b) EXAMPLE
A capacitive proximity probe may be used to sense non-magnetic units that are passing by on a conveyor,
glass bottles for instance. The probe could be powered from the +24 V from the input switch power supply. The
NPN transistor output could be taken to one of the assignable digital inputs configured as a counter.
