Modbus remote communication protocol
The master/slave protocol Modbus was first introduced by Modicon Inc. and is
widely accepted as a communication standard for industrial device controllers and
PLCs. For the protocol definition, refer to Section 1.4. Product documentation.
The implementation of the Modbus protocol in the relay supports both the RTU and
the ASCII link mode. Both the link mode and the line setting parameters are user-
configurable. The character codings of the link modes follow the protocol
definition. The RTU character format is presented in Table 5.1.15.-1 and the ASCII
character format in Table 5.1.15.-2:
