Modbus configuration
The 415U-2 provides Modbus TCP client/server and Modbus RTU
master/slave functionality for I/O transfer. Modbus TCP client,
Modbus RTU master, and Modbus TCP server/RTU slave can all be
supported simultaneously. When combined with the built-in Modbus
TCP-to-RTU converter, the 415U-2 can transfer I/O to and from
almost any combination of Modbus TCP or RTU devices.
The 415U-2 has predefined data areas for inputs and outputs and
the different I/O types (bits, words, long, floats, and so on), which
include the onboard input/outputs and are shared for both client and
server. For a full list of the available I/O and address locations see .
To change Modbus configuration parameters, click
