M238 System Functions Example The following table describes the output variable: Output Type Comment SetRTCDrift WORD Returns 00 hex if command is okay otherwise returns the ID code of the detected error. In this example, the function is called only once during the first MAST task cycle, 20 seconds is added to the RTC every Tuesday at 5:45:00 a.m.: VAR MyRTCDrift : SINT (-59..59) := 0; MyDay : DAY_OF_WEEK; MyHour : HOUR; MyMinute : MINUTE; END_VAR IF IsFirstMastCycle() THEN MyRTCDrift := 20; MyDay := TUESDAY; MyHour := 5; MyMinute := 45; SetRTCDrift(MyRTCDrift, MyDay, MyHour, MyMinute); END_IF 50 EIO0000000364 04/2012

Two kinds of Data Types are available: System Variable Data types are used by the System Variables (see page 9) of the M238 PLCSystem Library (PLC_R, PLC_W,...). System Function Data Types are used by the read/write System Functions (see page 23) of the M238 PLCSystem Library. What’s in this Chapter?
