2-2 SECTION 2: MONITOR SECURITY ACTIVITY
FUNCTION KEYS
Beneath the transactions display are the applicable function keys for each screen, with the key
actions shown next to the key numbers. For most function key actions, the system displays
messages confirming that the action has been completed, e.g., POLLER STOPPED.
In general, F1 is used to exit from the current screen, and F7 and F8 are used respectively to
display the previous screen and the next screen within the set of screens that apply to the particular
data item being controlled or when there are more items then will fit into a single screen.
DATA ITEM SELECTION
Use the up and down arrow keys to select the data item to be controlled, then press the applicable
function key for the system action to be taken.
CONTROL FUNCTIONS MENU
Pollers
The Control Pollers screen displays point ID, description, status.
Control Pollers Function Keys
F2 HALT. Stop a poller when work is to be performed on devices attached to the poller or to reload
a poller parameter following a change.
F3 RESTART. Restart the poller when work is completed (system displays messages announcing
each device attached to the poller as it comes back online). If there are devices with system or key
checksum errors, perform a reset to the device.
F4 DEV COMM. This function monitors communication between the pollers and the device pollers.
In normal operation, the devices are asked for information by the pollers many times a second,
and with a properly operating system the controller screen updates rapidly.
