Publication 1404-UM001D-EN-E - October 2004
I/O Operations 6-3
Setpoint Control
Set the Control source to a value of 7 to enable setpoints to control the
selected output.
Discrete I/O Control
Set the Control Source to a value of 8 to enable Ethernet Series B,
ControlNet, DeviceNet, or Remote I/O to have exclusive control over
the Powermonitor 3000 output via I/O messaging.
Forced Operation
You may over-ride automatic output control by issuing a force
command using the Display Module or by writing the appropriate
force command parameter in the Advanced Device Configuration
table. Forces override all other output control sources. If you force an
output either energized or de-energized, be sure to release the force
to re-establish your selected control source.
No Control Operation
You may also select no output control by selecting a value of zero (0)
for the Control source parameter. This mode enables only output
forcing.
TIP
If you cycle power to the Powermonitor 3000, all
output forces are released.
