<strong>M238</strong> System Functions ResetEventsNumber: Resets Events Number Function Description This function resets the number of events that have occurred since the last cold start, including those detected on inputs and HSC threshold compare events. NOTE: The number of events detected on inputs or HSC threshold detection is returned by the function GetEventsNumber (see page 27). Graphical Representation IL and ST Representation To see the general representation in IL or ST language, refer to the chapter Function and Function Block Representation (see page 71). I/O Variable Description The following table describes the output variable: Output Type Comment ResetEventsNumber BOOL TRUE if the counter has been reset to 0 with success. 48 EIO0000000364 04/2012
SetRTCDrift: Adjust the Real Time Clock Each Week <strong>M238</strong> System Functions Function Description This function adds or subtracts to the Real Time Clock a specified amount of seconds, each week, at the specified day of the week and time (hour:minute). NOTE: The SetRTCDrift function must be called at least once to update the parameters. Graphical Representation IL and ST Representation To see the general representation in IL or ST language, refer to the chapter Function and Function Block Representation (see page 71). I/O Variables Description The following table describes the input parameters: Inputs Type Comment RTCDrift SINT(-59..59) Correction in seconds (-59 ... +59) Day DAY_OF_WEEK (see page 66) Day of the week the day will be executed. Hour HOUR (see page 67) Hour of change. Minute MINUTE (see page 68) Minute of change. NOTE: If RTCDrift > 0, the execution of the change takes place at Hour:Minute:00 seconds. If RTCDrift < 0, the execution of the change takes place at Hour:Minute:59 seconds. NOTE: If the values entered for RTCDrift, Day, Hour, Minute exceed the limit values, the controller Firmware will set all values to their maximum values. EIO0000000364 04/2012 49
