Alarm fonts are specified per Alarm Category. Alarm Categories can be defined in the main project or in any of the includes. As with most parameters, the configuration in the include closest to the main project will take effect. A common scenario for PowerLogic SCADA projects is as follows: [Main Project] includes [ES_Common] includes [PLS_Include]. If the same Alarm Categories are defined in both ES_Common and PLS_Include, those configured in ES_Common will take effect.
To remove flashing from the alarm font, simply navigate to the relevant Alarm Category and remove the lowercase "f" from the font name. For example, the default Alarm On Font is ArialRed11f. To disable flashing, change this to ArialRed11. To view all available fonts, go to System > Fonts. If no existing font meets your needs, you can create your own in the same window and then assign it to an Alarm Category.
