Programming example
$MN_IPO_MAX_LOAD = 80
N01 $AN_SERVO_MAX_LOAD=0
N02 $AN_SERVO_MIN_LOAD=0
N03 $AN_IPO_MAX_LOAD=0
N04 $AN_IPO_MIN_LOAD=0
N05 $AN_SYNC_MAX_LOAD=0
N06 $AC_SYNC_MAX_LOAD=0
N10 IDS=1 WHENEVER $AN_IPO_LOAD_LIMIT == TRUE DO M4711 SETAL(63111)
N20 IDS=2 WHENEVER $AN_SYNC_TO_IPO > 30 DO SETAL(63222)
N30 G0 X0 Y0 Z0
...
N999 M30
The first synchronized action generates an auxiliary function output and an alarm, if the
entire time use limit is exceeded.
The second synchronized action generates an alarm if the share that the synchronized
action has of the IPO computing time (over all channels) exceeds 30%.

List of system variables relevant to synchronized actions

Note
The system variables listed previously, which can be addressed from synchronized actions
are given in the independent print version starting from SW-version 7.1:
/PGA1/ Parameter Manual, System Variables.
All system variables with the corresponding identifier X can be used (read/written) by
synchronized actions (SA). For further explanations on the properties of the system variables
in the main run, see Section 2.3 "Special main run variables for synchronized actions".
