3-1
Data Configuration
The MC Unit handles the following types of data.
1,2,3...
1.
System parameters
2.
Position data
3.
Monitor data
4.
Command area data
Note
Programs written in G language aren’t treated as data.
Note
The override function selection (6120) can be used only with Unit Ver. 1.15 or
later, and with Units whose model number ends in -V1.
Data Transfer Methods
The following methods are used to transfer the preceding data between MC
Units, to read monitor data, and to execute all functions in the command area.
Refer to the
CX-Motion Online Help
and also refer to
SECTION 4 Data Trans-
fer and Storage
for more details.
• Use CX-Motion.
• Execute IOWR/IORD instructions (INTELLIGENT I/O READ and INTEL-
LIGENT I/O WRITE instructions) from a ladder program.
• Execute IOWR instructions from a ladder program and write position data
that has been specified for transfer to the command area (addresses
6102/6103).
Specify the internal memory addresses of the MC Unit in hexadecimal to iden-
tify data when IOWR/IORD instructions are executed from a ladder program.
Refer to
Section 3-2 Determining the Task Configuration
for details.
Basic Data Concepts
System Parameters
Transfer system parameters created on the CX-Motion to the MC Unit (IOWR
instructions can be used to change system parameters while the CPU Unit is
running if needed).
Unit parameters
Memory management parameters
Axis parameters

address
System parameters
System parameters are comprised of unit
parameters, memory management
parameters, and axis parameters that
contain system information used in the
MC Unit, such as the number of axes
used, number of tasks, feed rates, and
operating ranges.
4000 to 4684
Position data
There are 2,000 addresses that indicate
positions. In G language, these are
identified as A0000 through A1999.
0000 to 1999
Monitor data
Monitor data is read-only data consisting
of various types of MC Unit data. such as
I/O monitor data that indicates the status
of I/O signals as well as status, tasks, and
axes error codes generated in the MC
Unit.
6000 to 6081
Command area
The command area is used to transfer
position data, write system parameters to
flash memory, execute automatic loading,
and perform other functions by writing
special command data using the IOWR
instruction.
6100 to 6120
