Monitoring and Troubleshooting Your

ControlNet System

Using the ControlNet WHO ACTIVEĊChannel Status Screen

Important: Keep the following in mind:

ControlNet WHO screens are available only when your programming

device is communicating through a 1784-KTC card, 1784-KTCx card,
or 1770-KFC interface on the ControlNet network.

When you view the WHO screens while your ControlNet system is

operating, you affect the performance of unscheduled I/O operations.

Follow the steps on the left to go to the ControlNet WHO ACTIVE—
Channel Status screen.
