Modbus TCP/IP for Modbus RTU/ASCII Network Environment Deployment
The Industrial Modbus Gateway can be a conversion bridge between the industrial equipment with the Modbus
RTU/ASCII Protocol and the administrator workstations that run the Modbus TCP/IP Protocol. The RS422/485
serial interface of the Industrial Modbus Gateway provides the Modbus RTU/ASCII operation mode and various
baud rate options to meet the demand of integration between the Modbus TCP/IP Protocol, Modbus RTU
Master/Slave Protocol and Modbus ASCII Master/Slave Protocol.
The advantage of having the Industrial Modbus Gateway is to assist users to build an industrial environment
between the Modbus TCP/IP Protocol and the Modbus RTU/ASCII Protocol easily, thus offering an application
solution to the industrial control equipment without Ethernet ports and the industrial control equipment can only
control through an industrial PC workstation or industrial control panel.
In addition, the effective integration solution of Modbus Ethernet devices, Modbus serial equipment or multi
Modbus master / slave in an industrial hybrid network brings the following:
■ Master mode supports up to 32 slave TCP connection requests
■ Slave mode supports up to 16 TCP master connections
