Explanation of function codes

 

 

Refer to the common part, function code and data part, in "3.11 
Explanation of function codes" for serial communication. ("Header", 
"Checksum" and "Trailer" are not required for Modbus / TCP 
communication. In addition, the "slave address" corresponds to the 
"Unit identifier" in Modbus / TCP, but this product identifies the 
fuselage by its IP address. Please refer to 5.12.11 for a concrete 
communication example. )
