Question about D2-DCM protocol


Thread Starter


Does anyone have experience in writing 3rd party drivers for Automation Direct products using their D2-DCM protocol?

We have a customer who wants to use our software to control their PLC. Our software allows us to write serial drivers to almost any instrument. But I've never worked w/ anything from Automation Direct. Is the protocol well published (if published at all)? I'm looking
for any documentation about this. I'd really like to hear anyone's opinion on the matter! Thanks.
The D2-DCM supports both the AutomationDirect (Koyo) Direct NET protocol and MODBUS RTU slave. Documentation for the Direct NET protocol is available on the AutomationDirect website. The MODBUS RTU slave protocol is ubiquitious and
documentation is available from many web sources, Modicon is a sure bet.
