Event Functons
A function used to carry out a given operation (event). They are not case-sensitive. They
are mainly used in conjunction with the conditional operator (?). The return values are
indicated below. The event is actually executed after the computation is complete.
• Execution successful: 1.0
• Execution failure:
0.0
• Invalid parameter: NaN
Functon Descrpton Example
AlarmAck() Issue an alarm acknowledge ch(1)>ch(2) ? AlarmAck() : 0
ResetMath() Reset the computation ch(00010)>=1.0 ? ResetMath() : 0
ResetTimer() Reset the values of all timers ch(00010)>=1.0 ? ResetTimer() : 0
ResetTimer(<timerNo>) Reset the specified timer ch(00010)>=1.0 ? ResetTimer(1) : 0
ResetTLog() Reset the TLOG computation ch(00010)>=1.0 ? ResetTLog() : 0
StartRec() Start recording ch(00010)>=1.0 ? StartRec() : 0
Valid after carrying out the
record start procedure.
Discarded if the recording is
already stopped (returns 1.0).
SplitRec() Move to the next record file ch(00010)>=1.0 ? SplitRec() : 0
Valid after carrying out the
record start procedure.
StopRec() Stop recording ch (00010) >=0 ? StopRec() : 0
Valid after carrying out the
record start procedure.
Discarded if the recording is
already started (returns 1.0).
Mark("mark") Create a mark. The text inside ch (00010) >=0 ? Mark("mark") : 0
the double quotation marks is
arbitrary.
• If the spacing between the execution of StopRec() and StartRec() is short, StartRec()
may not be executed. When repeating start/stop frequently, consider using the Split
function.
• The computed result at the time record start is executed is not necessary recorded to
the file.
