Description: System variable/value range/index
$A_YEAR
System time, year
$A_MONTH
System time, month
$A_DAY
System time, day
$A_HOUR
System time, hour
$A_MINUTE
System time, minute
$A_SECOND
System time, second
$A_MSECOND
System time, millisecond
$AC_TIME
Time from the beginning of block in seconds
This variable can only be accessed from synchronized actions
$AC_TIMEC
Time from the beginning of block in IPO clock cycles
This variable can only be accessed from synchronized actions
$AC_TIMER[n]
Timer – unit in seconds
Time is counted internally in multiples of interpolation cycle
cycle;
To start the counter variable, assign the value
$AC_TIMER[n]=<starting value>
To stop the counter variable, assign a negative value:
$AC_TIMER[n]=–1
The current time value can be read when the timer is running or
when it has stopped. When the timer is stopped by assigning the
value –1, the most up-to-date timer value is retained and can be read.
The dimension is defined in MD $MC_MM_NUM_AC_TIMER.
$AC_PRTIME_M "ProgramRunTIME-Main"
Set (initialize) the accumulated program runtime (main time)
$AC_PRTIME_A "ProgramRunTIME-Auxiliary"
Set (initialize) the accumulated program runtime (auxiliary time)
$AC_PRTIME_M_INC "ProgramRunTIME-Main-INCrement"
Increment the accumulated program runtime (main time)
$AC_PRTIME_A_INC "ProgramRunTIME-Auxiliary-INCrement"
Increment the accumulated program runtime (auxiliary time)
