Modbus application settings

9.1 

Modbus Gateway properties

The Modbus Gateway is an adapter application enabling conversions between serial
and network Modbus protocols. The gateway can operate on two modes; either
connecting serial masters to slaves behind the network or connecting network master
to serial slaves.

The gateway offers a number of core properties.

Supports Modbus RTU and Modbus ASCII serial protocols

Supports Modbus TCP, Modbus RTU over TCP, Modbus RTU over UDP,
Modbus ASCII over TCP and Modbus ASCII over UDP network protocols

Generates and filters out gateway exceptions

Routes traffic on the network, based on Modbus addressing, enabling intelligent
use of network resources

Makes automatic connection management

Enables multiple server sessions over network

Offers unlimited amount of Masters on serial or Network side

Offers 30 routes over network to slaves

9.2 

Modbus modes

Serial master to network slaves

When the Modbus master supports serial based Modbus, communication needs to
control slaves over a TCP/IP network. The device on the master side must be in the
“Serial master to network slaves” mode.
