XBT GC System Functions
Example
This example describes the three functions HMI_IsFirstMastCycle,
HMI_IsFirstMastColdCycle and HMI_IsFirstMastWarmCycle used
together:
NOTE: The functions must be used in MAST task otherwise initialization actions
might be performed more than once or never (an additional task might be called
several times or not called during 1 MAST task cycle).
IF HMI_IsFirstMastWarmCycle() THEN
(*This is the first Mast Cycle after a Warm Start: all
variables are set to their initialization values except the
retained variables*)
(*=> initialize the needed variables in order your application
to run as expected in this case*)
END_IF;
IF HMI_IsFirstMastColdCycle() THEN
(*This is the first Mast Cycle after a Cold Start: all
variables are set to their initialization values including the
Retains Variables*)
(*=> initialize the needed variables in order your application
to run as expected in this case*)
END_IF;
IF HMI_IsFirstMastCycle() THEN
(*This is the first Mast Cycle after a Start, ie after a Warm
or Cold Start as well as STOP/RUN commands*)
(*=> initialize the needed variables in order your application
to run as expected in this case*)
END_IF;]
