Special functions are used to access a specific value that is unique to a point. The value of the point can then be tested or assigned to other points. Since special functions are maintained by the system, they cannot be manually commanded to a different value. For information on the order in which special functions are evaluated, see the Order of Precedence.
NOTE:
Special functions cannot be used over the network.
PPCL supports the following special functions:
- Alarm priority (ALMPRI)
- Totalized value (TOTAL)
