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 the rate, total or grand total counts, one-for-one retransmit for input
pulses, 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 selectable to generate pulses at
a constant programmable frequency.
Alarms are available based on a Modbus PV, math channel, rate, total, or grand total. 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.
Output 1 and 2 Setup (OUT 1, OUT 2)
The function of open collector output 1 and 2 is configured using the Off (OFF), Pulse (PULSE), Alarm
(ALARM), and Timer (TIMER) menus detailed below.
In the Output 1 and 2 menus, use the Up button to scroll through the menu choices. Press Enter to make
