The following methods are used to access to each data. For further details,
refer to SECTION 5 Data Transfer and Storage (Page 212).
1. Use the Support Tool (CX-Motion-MCH).
2. Execute IOWR/IORD instructions (Intelligent I/O Write/Read) from the lad-
der program.
3. Variables can be used in the MC Unit's programs.
"IORD/IOWR Control Address" is the internal address to identify data when
IORD/IOWR instructions are executed from the ladder program. Global vari-
ables, input variables, output variables, or task variables cannot be accessed.
See 4-3 Variables (Page 105) for details.

during CPU Unit's operation can change the position data
as needed. It is possible to change the position data also
by using MC Unit's program.
Read with the IORD instruction from the ladder program

It is also possible to read it from MC Unit's programs.
transferred to the MC Unit. Using the IOWR instruction
during the CPU Unit's operation can change the system
parameters as needed. To use the IOWR instruction, the
axis whose parameters are to be changed has to be
specified in advance.
Global general variables, input variables, output vari-
ables, and task variables can be used in MC Unit's pro-
grams.
