5.2 System variables
After a block search, the coupling status and associated axis positions can be adjusted
subsequently by means of a system ASUB (asynchronous subroutine) "PROGEVENT.SPF".
System variables $P_SEARCH_MASL_C, $P_SEARCH_MASL_D and $AA_MASL_STAT
are available for this purpose; they can be used to alter the positional offset between the
coupled axes and the coupling status:
Identifier
$P_SEARCH_MASLC[slave axis identifier]
$P_SEARCH_MASLD[slave axis identifier]
$AA_MASL_STAT[slave axis identifier]

Meaning
This variable registers a change in the coupling state during the
SERUPRO block search.
This variable indicates the positional offset between the slave
and master axes at the instant the coupling was closed.
This variable indicates the current coupling state.
Value ≠ 0: "Master-slave coupling active"
In this case, it contains the current machine number of the
master axis and, if the NCU link is active (several operating
panel fronts and NCUs), also the NCU No. at the hundreds
position.
Example: 201 for Axis 1 on NCU2.
Special functions: Speed/Torque Coupling, Master-Slave (TE3)
