Meaning
Indicates whether the NX Units on the
Communication Control Unit can process
message communications. This status is
given as an array of BOOL data. The
subscript of the array corresponds to the
NX Unit number. A subscript of 0 indi-
cates the NX Bus Function Module and it
is always TRUE.
TRUE: Message communications possi-
ble.
FALSE: Message communications not
possible.
The status is FALSE for NX Units that are
set as unmounted Units.
Indicates whether the NX Units on the
Communication Control Unit are regis-
tered in the Unit configuration. This sta-
tus is given as an array of BOOL data.
The subscript of the array corresponds to
the NX Unit number. A subscript of 0 indi-
cates the NX Bus Function Module.
TRUE: Registered.
FALSE: Not registered.
If the Unit configuration information is not
registered by the Sysmac Studio, the sta-
tus is FALSE for all Units. The status is
TRUE for NX Units that are set as un-
mounted Units.
Meaning
Gives the NX Bus Function Module error
status.
This system-defined variable provides
the collective status of the NX Bus Func-
tion Module Master Error Status and NX
Bus Function Module Unit Error Status
for all NX Units.
