Honeywell Communication Protocol

What type of Communication Protocol is used in Honeywell TDC 3000?

TDC 2000/3000 used a proprietary protocol created by Honeywell. You can find it fully described here: https://www.honeywellprocess.com/library/marketing/product-manuals/HG03-400.pdf.

Before asking questions like this, please try to find your own answers the way I do - Google it! To find the above document I searched for TDC 3000 Data Hiway. The first item in the Google list was the above PDF.

Please clarify your application.

Internally I have no idea. Another post provided some info. The HPM I/O has it's own interface. TDC has a mux or bridge that talks Modbus for PLC's.

If you google it you will find literature. Sign up with Honeywell's Automation web site, they have all their manuals online.

good luck
