Instruction Manual

Open Collector Outputs (
OUTPUT
)
The scanner is equipped with two NPN open collector
outputs that may be set up for pulse outputs, alarms,
timed pulses, or turned off.
Pulse outputs can be based on a Modbus PV value,
or math channel value. Both outputs may be used to
generate a quadrature output based on any pulse
menu output type. An output test mode is also se-
lectable to generate pulses at a constant programma-
ble frequency.
Alarms are available based on a Modbus PV or math
channel. The alarm status will show on the display
even if the output is not wired. The outputs may also
be forced on or off.
A timed pulse output generates constant pulses at a
specified frequency and on time.
The output may be disabled by selecting
Off
.
