Comment data and section data could not be stored in the actual PLC when a
project was downloaded from the CX-Programmer to the CPU Unit unless
both a Memory Card and EM file memory were available.
A comment memory is provided within the CPU Unit's internal flash memory.
Therefore, the following comment/section data can be stored in and read from
comment memory even if neither Memory Card nor EM file memory are avail-
able.
• Symbol table files (including CX-Programmer symbol names and I/O
comments)
• Comment files (CX-Programmer rung comments and other comments)
• Program index files (CX-Programmer section names, section comments,
and program comments)
CX-Programmer Ver. 5.0 or later
Project
Transfer
When downloading projects using the CX-Programmer Ver. 5.0, either of the
following storage locations can be selected as the transfer destination for
comment data and section data.
• Memory Card
• EM file memory
• Comment memory (in CPU Unit's internal flash memory)
Note When using CX-Programmer Ver. 4.0 or earlier, this data is stored in either the
Memory Card or EM file memory, whichever is available. If neither the Mem-
ory Card nor EM file memory is available, the comment/section data cannot
be stored in comment memory.
The simple backup function could not be used to back up comment data or
section data.
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 symbol names and I/O
comments)
Comment/section data can be stored in the actual PLC
when downloading projects.
