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
Use the following CX-Programmer procedure to create variable table files or
comment files on Memory Cards or in EM file memory.
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.)
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.
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).
