PC protocol for Fx2n rs232 comms

[Guest Alan B]

I need to read contents of registers and condition of markers from PLC using RS232 comms. I knows the comms port is working, can anyone help with some VB6 code and an explanation of how it works? Thanks

You realize without a programming cable with converter or a FX2N-232BD you're looking at a PLC with an RS422 comm port right? There are several people on the internet (and Ebay) offering ActiveX controls to do the comm cheaply. If you find a good or free one, let me know. I've got to start trying to do that shortly too.

Hey, Chris, you got the protocol?

[Crossbow 295]

Should be able to download the protocol information from www.meau.com, as the MC protocol is open. I probably have the document on my computer at work. If I find it, I will upload it.

could you please send me at sorrrrrin@yahoo.com this protoco (for fx2n), or a link..? I need it very urgent :( thanks very much.

It's in the downloads section here under Mitsuibshi manuals. Look for the MC Protocol guide. Or go to www.meau.com and search it out.

[Guest Guest_sorin]

i have downloaded "Q corresponding MELSEC Communication Protocol"... does it work for PLC FX1N too? i'm newbie. i wondering!

[Crossbow 295]

I believe the Q protocol is similar but has some more options as the Q has more memory and memory areas. i would recommend you get the MELSEC MC Protocol reference manual from the MRPLC.Com downloads section to be sure you're talking correctly.
