Programming Devices (Including Programming Consoles)

The backup function can be used to store all of the CPU Unit's data (the entire
I/O memory, program, and parameter area) on the Memory Card without a
Programming Device. If a problem develops with the CPU Unit's data, the
backed-up data can be restored immediately. (Not supported by CS-series
CS1 CPU Units that are pre-EV1)
The CX-Programmer can be used to save program symbols and I/O com-
ments in symbols table files called SYMBOLS.SYM in Memory Cards or EM
file memory.
When CX-Programmer version 5.0 or higher is used with a CS/CJ-series CPU
Unit with unit version 3.0 or later, it is also possible to select the comment
memory, which is in the CPU Unit's internal flash memory.
The CX-Programmer can be used to save program rung comments in com-
ment files called COMMENTS.CMT in Memory Cards or EM file memory.
When CX-Programmer version 5.0 or higher is used with a CS/CJ-series CPU
Unit with unit version 3.0 or later, it is also possible to select the comment
memory, which is in the CPU Unit's internal flash memory.
The following procedures are used to read, write and otherwise work with files
using the following methods.
• Programming Devices
• FINS commands
• FREAD(700), FWRIT(701), and CMND(490) instructions in the user pro-
gram (CMND(490): Not supported by CS-series CS1 CPU Units that are
pre-EV1.)
• Replacement of the entire program using AuxilIary Area control bits (Not
supported by CS-series CS1 CPU Units that are pre-EV1)
• Automatic transfer at startup
• Backup function (Not supported by CS-series CS1 CPU Units that are
pre-EV1)
The following operations are available through Programming Devices.
Operation
Reading files (transfer from file memory
to CPU Unit)
Writing files (transfer from CPU Unit to file
memory)
Comparing files (compare files in the
CPU Unit and file memory)
Formatting file Memory Cards

EM files
Changing file names
Reading file memory data
Deleting files
Coping files
