can anyone help me in doing an Honeywell st-71 to system 57 through modbus master slave communication..?
 
Help us.

What is a Honeuywell ST-71 (functionally)?

Can you provide a link to the manual where it describes ST-71 comm capability?

Can you provide a link to the manual/document that provides comm information on the System 57?
