Section 4-2. The normal network message display when there are no active system events is as
follows:

5-8.3.1
OPERATOR-DRIVEN MENU STATE
The system enters the Menu State when an operator presses the 0 Key and enters the appropriate
password as described in Section 4-8. The operator will be prompted to enter a network node
number. The requested menu will be accessible if the node number corresponds to:
•
The control unit whose display is being utilized
•
Another control unit in the same group as the control unit whose display is being
utilized
•
Any control unit in a network configured for global operation
•
The control unit whose display is being utilized is defined as Group 0
5-8.3.2
EVENT-DRIVEN STATES
A networked control unit will enter one of the event-driven states (pre-alarm, alarm, supervisory, or trouble)
when it is configured as Group 0 or when the event that occurs is:
•
Resident in the control unit or its associated peripheral devices
•
From another control unit in the same group as the control unit
•
From any control unit in a network configured for global operation
•
From a control unit in group 0 if Process Group 0 Events is configured
5-8.3.3
NETWORK OUTPUTS ACTIVATION
Control unit or SLC outputs can be activated via execution of operating instructions contained in each
networked control unit’s event output control (EOC) program. The EOC program for a particular
control unit is triggered by any event that transitions it from the Normal Mode to any of the Off-
Normal operating states discussed in Section 4-10. The control unit must be configured to selectively
receive and respond to the event as described Section 5-8.2
or the network must be configured for
global operation.
