Introduction
This tutorial is designed to explain the transfer process of compact flash memory cards for CS1/CJ1 PLCs.
Saving configuration files / program on the CF memory card
There are several ways to create / save the configuration of an machine, either with or without using a PLC.
Method 1: "Backup" of machine using CJ1 / CS1:
- Insert the CF card
- Switch the switch 7 to ON
- Press MCPWR for 3 seconds
- When the transfer finishes, LEDs Busy and MCPWR turn off
- Switch the switch 7 to OFF
Method 2: With a different PLC and using CX-Programmer:
- From the CX-Programmer I/O editor table, add the cards corresponding I/O to the desired configuration and then move the table in the PLC. The transfer is possible in only two cases: - The actual configuration of PLC I / O is identical to one created. - The PLC is equipped with no map I / O and has no table I / O recorded.
- Insert a CF memory card
- Run a backup as described above
Method 3: Using CX-Simulator instead of a PLC:
- Run CX-Simulator
- Open the memory card manager
- Make a copy-and-paste of the data files involved with the renaming as described in the table below.
- Then copy the files from the virtual memory of the PLC to a CF card:
Method 4: With CX-Programmer only (without PLC):
- Insert a CF card into the appropriate drive of the PC
- Run CX-Programmer
- Right click on the PLC, select from the context menu ... Forward. To file.
- Copy / paste the generated files into the CF memory card.

Warning: This operation does not achieve all of the data (program and comments only). Automatic loading CF -> PLC requires several files (see next section "Automatic Transfer") |
Automatic transfer from CF card to the CJ1 / CS1 PLC
There are 3 loading procedures:
- RESTORE: To restore on power up all data previously saved by a backup
- AUTOEXEC: Used to load at power and selectively programs / parameters and partial memories
- REPLACE: Restore the Program alone on power up. Note: This function requires a CPU V2 or higher
| AUTOEXEC | RESTORE | REPLACE | Description | |
| Program | AUTOEXEC.OBJ | BACKUP.OBJ | REPLACE.OBJ | User program |
| Data | AUTOEXEC.IOM | BACKUP.IOM | DM special cards (D20000-D32767) | |
| ATEXECDM.IOM | BACKUPDM.IOM | DM users (D0-D19999) | ||
| ATEXECE*.IOM | BACKUPE*.IOM | EM memory bank (0 to C from the CPU) | ||
| BACKUPIO.IOR | CIO, WR, HR, AR, T / C val. Current | |||
| Parameters | AUTOEXEC.STD | BACKUP.STD | PLC Configuration, table I / O, routing tables, table data-link | |
| Special | BACKUP**.PRM | Data / maps specific program (Protocol macro, etc.). |
Key: The files in bold type are essential for the proper conduct of the proceedings. Non-bold filenames are optional.
Procedure for AUTOEXEC:
- Rename files necessary AUTOEXEC (retaining the extension) *
- Turn off the PLC
- Switch the switch 2 to ON
- Power on the PLC
- When the transfer is complete the LED Busy turns off
- Switch the switch 2 to OFF
Procedure for RESTORE:
- Turn off the PLC
- Insert the CF card in the PLC
- Switch the switch 7 to ON
- Turn on the PLC power
- When the transfer is complete, the BKUP LED turns off
- Switch the switch 7 OFF
 |
Note: If SW2 and SW7 is ON at power, the RESTORE procedure takes precedence over the procedure AUTOEXEC |
Procedure for REPLACE:
- Rename the file necessary REPLACE.OBJ
- Turn off the PLC
- Switch ON switch 2
- Turn on PLC the power
- When the transfer is complete the LED Busy turns off
- Switch OFF switch 2
Program hot transfer (from CPU-V3)
- Rename the program file (eg ABC.OBJ)
- Authorize this transfer by placing the word
A5A5inA651 - Specify the file name in the words
A654toA657(ex:4142 4320 2020 2020) - Force the bit
A650.15ON to execute the transfer
|
Note: At the end of the transfer words A650-657 and the bit A650.15 are re-initialized |
