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.
