Synchronized Action Parameters $Ac_Param[N]; Arithmetic Parameter $R[N] - Siemens SINUMERIK 840D sl Programming Manual

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.

Example of synchronized action parameter $AC_PARAM[n]
$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 parts program and synchronized
actions.
