I/O Operations Chapter 6

3. Select a maximum pulse rate.

This should be between 2 and 5 pulses per second for a
two-wire KYZ connection and between 2 and 10 pulses per
second for a three-wire connection. Let

s use a three-wire KYZ

connection and a pulse rate of 4 pps.

4. Compute the output scale by dividing the result of step 2 by the

result of step 3 and rounding to the nearest integer.

For our example, we

ll set the output scale to 70.

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, ControlNet,
DeviceNet, or remote I/O networks to have exclusive control over the
power monitor output via I/O messaging.

Forced Operation

You may over-ride automatic output control by issuing a force
command by 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.

TIP

If you cycle power to the power monitor, all output forces are
released.
