Is it really cx-programmer version 9.5?

Oops

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?

Hallo, 105 isn't value it is CIO address. It will be #105 (Hexa) or &105 (Decimal).

Thank you for the explanation. It made me learn to use IR, DR. I think it will be a good solution for my program.

Thank you very much. Now it's quite understandable for me .  I'll try it tomorrow.

Yes, I know it. But I need make it in FB ( It is onpy example. It will be more comlex function with start address as parameter - I will set start address on input FB and fuction use address space from it.)

Hi all, how can I use indirect addressing in FB for CPU CJ2. For instance in this simple example (without using D500)
