Backup program CQM1H CPU51, 21

[A2N]

Dear Sirs, I am trying to make a backup of a CQM1H CPU51 PLC with the CX-Programmer PLC Backup Tools, but it does not allow me to select this CPU model.
Could someone send me a previous version?
It only allows me CJ1x, CPxx, CSx and NSJ

 

Thanks you very much

Using the backup tool for the CQM1H will not be possible with any version. This function was added somewhere during the life cycle of the CS/CJ PLCs. It was intended to restore the PLC program, PLC settings, I/O table, and memory in one simple step.

You can make a complete backup doing the following:

1) PLC > Transfer > From PLC

2) Go to Settings in the project tree. Click Options > Transfer from PLC.

3) a) Go to Memory in the project tree.

     b) Double Click HR and DM.

     c) Click Online > Transfer from PLC.

     d) Check HR and DM then click Transfer From PLC. (Make sure Transfer Range is set to All)

     e) Select File > Save in Project.

The CQM1H does not have an I/O Table so that will not be necessary. You may want to verify if any Non-Default Expansion Instructions are used. I don't know how to back them up with CX Programmer, or if it's necessary. It's been a while since I've dealt with them.
