# Timer functionality

The #TIMER functionality is available for realtime cycles. The measured times are saved to the realtime variables V.RTG.TIMER[]. Realtime timers are different from decoder timers.

## Programing Example

#TIMER functionality

; Output variables

$FOR P1 = 0, 4, 1

#MSG SAVE EXCLUSIVE ["V.RTG.TIMER[%d] = %f", P1, V.RTG.TIMER[P1]]

$ENDFOR

; Define realtime cycle

#RT CYCLE [ID = 17 SCOPE = PROG]

$IF ONCE 1 < 2

#TIMER START SYN [ID = 0] ; Start Timer 0

#TIMER START SYN [ID = 2] ; Start Timer 2

$ENDIF

#RT CYCLE END

#FLUSH WAIT

; please wait

#TIME 1.5

; Define realtime cycle

#RT CYCLE [ID = 18 SCOPE = PROG]

$IF ONCE 1 < 2

#TIMER STOP SYN [ID = 0] ; Stop Timer 0

#TIMER READ SYN [ID = 0] ; Read Timer 0

#TIMER READ SYN [ID = 2] ; Read Timer 2 without stopping

$ENDIF

#RT CYCLE END

#FLUSH WAIT

; Output variables

$FOR P1 = 0, 4, 1

#MSG SAVE EXCLUSIVE ["V.RTG.TIMER[%d] = %f", P1, V.RTG.TIMER[P1]]

$ENDFOR

; End main program

## Attention

Only asynchronous #TIMER commands are permitted. All #TIMER commands in realtime cycles must be marked as synchronous by the keyword SYN.
