Hi, guys I'm trying to upload or download program from CPM1A-40CDR-D-V1, but still does not work. PLC : CPM1A-40CDR-D-V1 Expansion: CPM1A-8ER Software : CX-Programmer V4.03 Interface Unit : CPM1-CIF01 USB to Serial (RS-232) Prolific

I do not know about the Prolific converter - some work some do not - I use the Omron one. It is probable your serial cable is incorrect - Omron do not use a standard serial cable. Here is a link to the correct cable http://forums.mrplc.com/index.php?app=downloads&showfile=74

No - there are many cable configurations in the file - use C200HS-CN220-EU and make your own. I suggested that the Prolific USB/serial cable may or may not work. I use the Omron CS1W-CIF31 USB/serial converter - it works with every PLC I have ever connected - not cheap but is tested and works.

so, if I use CS1W-CIF31 USB/serial converter , I still need to use CPM1-CIF01. Order as follows:- Laptop (CX-Programmer V4.03) + CS1W-CIF31 USB/serial converter(c/with driver) + CPM1-CIF01 + CPM1A-40CDR after this I can upload file 'CX-Programmer Project'

And the cable.

I know you can plug your Prolific adapter into the CPM1-CIF01. But the pins do not match electrically. You still need the C200HS-CN220-EU cable. Get out your soldering pencil and make one!
