Re: [foxboro] FBM224 and Atlas Copco Elektronikon

Free advice.

Before attempting any such project, buy a line analyzer. Today's
implementation is a piece of software that runs on a laptop with a =
cable
that lets the PC site between the two devices.

The software allows the PC to monitor the communications and it will =
greatly
ease your work.

I simply can't make serial links work without such equipment.

Here's a web page that you can use to see what I'm talking about:

http://catalog.blackbox.com/BlackBox/Templates/blackbox/mainscreen.asp

I bought Serialtest ComProbe (Sync/Async) for Windows 95/98/Me/2000 or
Windows NT  TD115V-R3 =20

With this and a little knowledge of the Modbus protocol, you'll figure =
it
out.

Without this? It's going to take awhile.

Has anyone out there worked with Modbus communications between the =
FBM224
and the Atlas Copco Elektronikon Sequencer?
I have a good communications line between the two and still no talking
taking place.

Anyone have any ideas?  Like dip switch settings on the FBM224 TA? =20

My next step may be to have the Atlas Copco folks come in and assure me =
they
are trying to send information.

Thanks
