The following ControlNet related fields may be placed on an

application screen using internal tags. These read only fields are

maintained by the network keeper and do not appear unless added to

a screen. Refer to Displaying ControlNet Internal Tag Data (next

section).

Network Update Time (NUT)

Displays the network update time in milliseconds.

UMAX Node

Displays the ControlNet network’s Unscheduled Maximum node

address (UMAX) setting. The UMAX node is the highest

ControlNet address that can communicate during the unscheduled

portion of the network update interval. The PanelView node address

must be set to a value less than or equal to the UMAX setting to

enter on to the network.
