VII. Setting of other working parameters 

7.1 Parameter setting and protocol of full-function communication port 

The 2# communication port is a full-function communication port, and the 

communication  mode,  address  and  baud  rate  can  be  set.  It  supports  top-loose 
protocol, standard Modbus RTU protocol, multiple continuous transmission modes, 
etc. 

The F parameters involved are F06 (communication mode), F07 (communication 

address) and F08 (communication baud rate). Please refer to the specific setting 
method.

Section 5.5

. Communication mode F06 determines the protocol currently used 

by this communication port. See the following table for details.
