10.3.6 Synchronized action parameters ($AC_PARAM[n])
Function
The synchronized action parameter $AC_PARAM[n] is used for calculations and as
intermediate memory in synchronized actions. These variables can either be saved in the
memory of the active or passive file system.
Synchronized action variable: Data type:REAL
These parameters exist once in each channel under the same name.
$AC_PARAM[n]
Arithmetic variable for motion synchronized actions (REAL)
$MC_MM_NUM_AC_PARAM
Machine data for setting the number of parameters for
movement synchronized actions up to a maximum of 20000.
n
Array index of parameter 0n
Example of synchronized action parameter $AC_PARAM[n]
Program code
$AC_PARAM[0]=1.5
$AC_MARKER[0]=1
ID=1 WHEN $AA_IW[X]>100 DO $AC_PARAM[1]=$AA_IW[X]
ID=2 WHEN $AA_IW[X]>100 DO $AC_MARKER[1]=$AC_MARKER[2]
10.3.7 Arithmetic parameter ($R[n])
Function
This static array variable is used for calculations in the part program and synchronized
actions.
Syntax
Programming in part program:
REAL R[n]
REAL Rn
Programming in synchronized actions:
REAL $R[n]
