Using File Memory Section 5-3
Configuration: CPU Unit + 1 Motion Control Unit (See note 2.)
Note 1. Tested with the Serial Communications Unit's internal parameters at max-
imum capacity.
2. Tested with a program of the following size in the Motion Control Unit
• 8 tasks and 20 axes
• Main program: 2,790 blocks
• Sub programs: 990 blocks
• Cam tables: 800 points
Creating Variable Table
and Comment Files
Use the following CX-Programmer procedure to create variable table files or
comment files on Memory Cards or in EM file memory.
1,2,3... 1. Insert a formatted Memory Card into the CPU Unit or format EM file mem-
ory.
2. Place the CX-Programmer online.
3. Select Transfer and then To PLC or From PLC from the PLC Menu.
4. Select either Symbols or Comments as the data to transfer.
Note If a Memory Card is installed in the CPU Unit, data can be transferred only
with the Memory Card. (It will not be possible with EM file memory.)
EM File Memory
Using a Programming Device
1,2,3... 1. Use PLC Setup to specify the starting EM bank to convert to file memory.
2. Use a Programming Device to initialize EM file memory.
3. Use a Programming Device to name the CPU Unit data (user program, I/O
memory, parameter area), and then save the data to EM file memory.
4. Use a Programming Device to read the file in EM file memory to the CPU
Unit.
Using FREAD(700)/FWRIT(701)/CMND(490)
1,2,3... 1. Use PLC Setup to specify the starting EM bank to convert to file memory.
2. Use a Programming Device to initialize EM file memory.
3. Use FWRIT(701) to name the file in the specified area of I/O memory and
then save the file to EM file memory.
4. Use FREAD(700) to read the file from the EM file memory to I/O memory
in the CPU Unit.
EM file memory operations can be executed by issuing FINS commands to
the local CPU Unit with CMND(490).
