We monitor the alarm bit with an Independent Sequence block. When the bit turns, we set the DMCMD global to the overlay name or other command we want the WP's to run. Here is some sample code: IF ML_TRIGGER THEN :2WP51B DMCMD:="dmcmd run /opt/coa/prog/second/ml_popup"; :R1WPA1 DMCMD:="/opt/coa/over/second/mliquor/ml_popup.fdf"; In the first case, the display manager named 2WP51A will run a script file, in the second case, the display manager named R1WPA1 will load a overlay file.
