10.1.1 Programming and command elements
Function
A synchronized action is programmed on its own in a
separate block and triggers a machine function in
the next executable block (e.g. traversing movement
with G0, G1, G2, G3; block with auxiliary function
output).
Synchronized actions consist of up to five command
elements each with a different task:
ID n um ber:
Scope of validity
Vocabulary word:
Scan frequency
opt. G code

Example:
ID=1
WHENEVER
$A_IN[1]==1
DO
$A_OUT[1]=1
Synchronized action no. 1:
whenever
input 1 is set
then
set output 1
