Downloading to Omron CQM1 problem.

Hi guys! New here. Great site... yada yada yada... .

I found this old Omron CQM1 PLC lying around in our store and
started to play around with it. Now, I can upload the program and
I can do online changes, but when I try to download a new program,
it says. "Set Exp Fun - Dip Switch error" .
Why does it do this?

I played around with the dip switches with no luck.

I'm fairly new to Omron and teaching myself along the way.

Can some1 please shed some light...

Dip Switch 4 On:

If you do not need to download expansion functions, untick the "expansion function" download box when you go to download.'

Thanx guys, went through the manuals again and found it. All going smooth now. But b warned, u WILL hear from me again.
