On the MC Unit, the following signals can be used as I/O variables; I/O con-
nector signals of the MC Unit, the bit areas/data areas between the CPU Unit
and the MC Unit, and I/O signals between MECHATROLINK-II devices and
the MC Unit.

The R/W columns indicate the restriction on reading and writing from a pro-
gram in the MC Unit. Of the output variables, the status output area cannot be
written from the user program.
Writing data from a program in the MC Unit to the input variables linked to bit
areas/data areas between the CPU Unit and the MC Unit enables the MC Unit
to control the Unit, tasks, and axes.
Writing data from a program in the MC Unit to the output variables linked to
the output signals of the MC Unit's I/O connector or MECHATROLINK-II out-
put devices enables the MC Unit to control output signals.
