SetTimer
Sets the time-out value of timer T (1–32). Timer values are specified in 0.01-second intervals (1= 10 ms, 100 =
1 second). For one-shot timers, the SetTimer function must be called again to restart the timer once it has expired.
Method Signature:
function SetTimer (T : Integer ; V : Integer) : Syscode;
Parameters:
[in] T Timer number
[in] V Timer value
SysCode values returned:
SysInvalidTimer The timer specified by T a not valid timer.
SysOK The function completed successfully.
SetTimerDigout
SetTimer Digout is used to provide precise control of state changes for timers using TimerDigoutOff or
TimerDigoutOn modes. The state of the specified digital output (slot S, bit D)is changed when timer T (1–32)
expires.
Method Signature:
function SetTimer (T : Integer ; S : Integer ; D: Integer) : Syscode;
Parameters:
[in] T Timer number
[in] S Digital I/O slot number
[in] D Digital I/O bit number
SysCode values returned:
SysInvalidTimer The timer specified by T a not valid timer.
SysOK The function completed successfully.
Example:
SetTimer(1,100); -- Set value of Timer1 to 100 (1 second)
SetTimerMode(1,TimerDigoutOn); -- Set timer mode to turn on the digital output
SetTimerDigout(1,0,1); -- Set which digital output to control (slot 0, bit 1)
StartTimer(1); -- Start timer
SetTimerMode
Sets the mode value, M, of timer T (1–32). This function, normally included in a program startup handler, only
needs to be called once for each timer unless the timer mode is changed.
Method Signature:
function SetTimer (T : Integer ; M : TimerMode) : Syscode;
Parameters:
[in] T Timer number
[in] M Timer mode
TimerMode values sent:
TimerOneShot Timer mode is set to one-shot.
TimerContinuous Timer mode is set to continuous.
TimerDigOutOff One-shot timer sets a digital output off when the timer expires.
TimerDigOutOn One-shot timer sets a digital output on when the timer expires.
SysCode values returned:
SysInvalidTimer The timer specified by T is a not valid timer.
SysInvalidState The timer specified by M is a not valid timer mode.
SysInvalidRequest The slot or bit number configured is not a valid digital output .
SysOK The function completed successfully.
