2.3 Special real-time variables for synchronized actions
System variables
$AN_SYNC_ACT_LOAD
$AN_SYNC_MAX_LOAD
$AN_SYNC_TO_IPO
$AC_SYNC_ACT_LOAD
$AC_SYNC_MAX_LOAD
$AC_SYNC_AVERAGE_LOAD
$AN_SERVO_ACT_LOAD
$AN_SERVO_MAX_LOAD
$AN_SERVO_MIN_LOAD
Overload information
MD11510 $MN_IPO_MAX_LOAD is used to set the net IPO computing time (in % of IPO
cycle) starting from which the system variable $AN_IPO_LOAD_LIMIT is to be set to TRUE.
If the current load falls below this limit, the variable is again set to FALSE.
If the MD is 0, the entire diagnostic function is deactivated. The user can evaluate
$AN_IPO_LOAD_LIMIT to define a specific strategy for avoiding plane overflow.
Writeable system variables
The system variables described above can be written from synchronized actions:
System variables
$AN_SERVO_MAX_LOAD
$AN_SERVO_MIN_LOAD
$AN_IPO_MAX_LOAD
$AN_IPO_MIN_LOAD
$AN_SYNC_MAX_LOAD
$AC_SYNC_MAX_LOAD
On every write access, these variables are reset to the current load, regardless of the value
written.
