7.1 Example: Customize
When configuring Alarms (Section 6.5.3), Signals (6.6.2), or Controls (6.7), an option to CUSTOMIZE will
be presented at the bottom of the screen, see Figure 95 below. This enables the Supervisor to program
separate triggering equations into the CXC software. The equations may reference any combination (up

utilizing logical and arithmetic arguments that simulate the functionality of a programmable logic control-
ler (PLC).
