HOW THe ANNUNCIATOR WORKS
The Annunciator module appears as an output module to the SCADA 3000. When the system
is powered up, the main unit will scan the external module network and add the Annunciator
to its list of modules at the address specified by the Bus Address jumpers. An icon for the
Annunciator will also appear on the main unit screen.
The Annunciator module provides eight LED indicators that can be used to display the status
of I/O points, system variables, or alarm conditions. The LEDs can be forced on (Red) or off
(Amber) through the Annunciator module programming screen, or they may be controlled
automatically using a C-program or Ladder program. The eight LEDs appear in the program-
ming software as digital outputs numbered from 0–7. To access the Annunciator program-
ming screen, click on the Annunciator icon from the Main Unit form or select Modules , then
Annunciator from the Main Menu.
