$A_XFAULTSI Bit 0=1:
In a crosswise data comparison
between NCK and drive of any
particular safety axis, an actual
value error was detected.
Bit 1=1:
In the crosswise data comparison
between NCK and drive of any
axis, an error was detected and
the delay time (<>0) until STOP B
is initiated for this axis is either
running or has already expired.
$VA_XFAULTSI[axi Bit 0=1:
s] The crosswise data comparison
for this axis between NCK and
drive has detected an actual value
error.
Bit 1=1:
In the crosswise data comparison
between NCK and drive of this
axis, an error was detected and
the delay time (<>0) until STOP B
is initiated for this axis is either
running or has already expired.

$A_PLCSIIN[n] Single- -channel direct communi-
cation between NCK and PLC- -
SPL. Signals can be written by
the PLC and read by the NCK.
$A_PLCSIOUT[n] Single- -channel direct communi-
cation between NCK and PLC- -
SPL. Signals can be read by the
PLC, written to and read from the
NCK.
