CJ2 CPU Unit Software User’s Manual
A comment memory is provided within the CPU Unit's internal backup memory. The following com-
ment/section data can be stored in and read from comment memory even if neither Memory Card nor
EM file memory are available.
• Symbol table files (including CX-Programmer symbols and I/O comments, but not network symbols)
• Comment files (CX-Programmer rung comments and other comments)
• Program index files (CX-Programmer section names, section comments, and program comments)
When downloading projects, either of the following storage locations can be selected as the transfer
destination for comment data and section data.
• Comment memory (in CPU Unit's backup flash memory)
•Memory Card
• EM file memory
The following files stored in comment memory can be backed up to a Memory Card when a simple
backup operation is executed, or the files can be restored to comment memory from the Memory Card.
• Symbol table files (including CX-Programmer symbols and I/O comments, but not network symbols)
• Comment files (CX-Programmer rung comments and other comments)
• Program index files (CX-Programmer section names, section comments, and program comments)
This enables backup/restoration of all data in the CPU Unit including I/O comments if an error occurs or
when adding a CPU Unit with the same specifications without requiring the CX-Programmer.
