10.3.5 Synchronized action marker ($AC_MARKER[n])
Function
The array variable $AC_MARKER[n] can be read and written in synchronized actions. These
variables can either be saved in the memory of the active or passive file system.
Synchronized action variable: Data type INT
$AC_MARKER[n] Channel-specific marker/counter, INTEGER data type
$MC_MM_NUM_AC_MARKER Machine data for setting the number of channel-
specific markers for movement synchronized actions
n Array index of variables 0-n
Example of reading and writing marker variables
Program code
WHEN ... DO $AC_MARKER[0] = 2
WHEN ... DO $AC_MARKER[0] = 3
WHENEVER $AC_MARKER[0] == 3 DO $AC_OVR=50
