9.1 MONITOR I/O
The Monitor IO menu option from the
2850+ menu allows the user to see sev-
eral screens which provide live readings
of both the analog and digital aspects
of the PLC. These screens are extremely
useful for troubleshooting whether or
not sensors are working as the values
displayed are irrespective of settings
selected on the 2850+ controller.
The Monitor IO page displays Embed-
ded IO, or monitors the IO of the PLC
and to some extent the 2008 modules.
9.2 ANALOG IO MONITOR
The analog IO screen displays the current
analog values for the controller and can be
used for troubleshooting purposes. The dis-
played value is the number of counts re-
ceived. Divide by 1000 and that will corre-
spond to the mA received.
9.3 PLUGIN RELAY OUTPUT
Plugin relay output page displays the status of
the relays of the plugin modules (located on
the top of the PLC). These are primarily used
for zone control. They can be toggled on/off
even if the channel is running.
