For PLC all is set by Dip switch

Try to use default serial setting - PLC DIP switch 5 ON. The default settings for the RS-232C port are: host link mode, 1 start bit, 7 data bits, even parity, 2 stop bits, and a baud rate of 9,600 bps.  Im using OMRON interface USB - serial CS1W-CIF31. But the price

You need to use original omron serial cable (or make it) from converter to PLC due to non standart pinout (see chelton message)

You have to buy new CF card (max 1 GB) and use it without any formating (never format this card).

Is it really cx-programmer version 9.5?

In the machine is array with size 100 (ARRAY [1..100]]. Can I simply change it to 200 without data loss?

Hi,  cpm1a-40cdr-a-v1  has relay outputs. Contact connects corresponding output with COM.

My v 1.24 is working too.

Oh, that may be it. I will have to contact the supplier. Many thanks for clarifying.

Thanks for your reply. Original PLC is working without problems. I wanted to make a backup. There are no problems to make upload from other machines (about 10). By Synchronize  (from PLC) I see message: emty rungs. Maybe some protection from supplier?

Hi all, I uploaded SW from working PLC NJ301 1100 v 1.9. Uploading worked, but when I tried to open program, all rungs were empty (see picture). Does anyone know the cause?

PLC? memory card? switches setting?
