MGate MB3000 Modbus Gateway User Manual 84
Serial Redirector
An advanced multiport MGate model (MB3270/MB3270I) can be inserted into the serial system, with the
slaves connected to one serial port and the master to another serial port. The advanced gateway allows
Ethernet masters to communicate with the serial slaves, and it also provides a serial redirector function that
simultaneously allows the serial master to continue controlling the slaves.
Integrate Modbus RTU, ASCII, and TCP at the
Same Time
There can be a wide range in number, type, and sophistication of devices on the factory floor. The most
common devices are simple serial-based meters, which report certain information relating to factory
environment or equipment. However, other Modbus serial slaves may be as complex as a manufacturing
machine or a PLC controller.
When integrating these devices, there may be issues if different serial environments are used for different
devices. One system may use a different baudrate than another, or may use Modbus ASCII instead of
Modbus RTU. The MGate MB3000 allows the different Modbus systems to be integrated into one network,
regardless of the protocol or communication parameters.
