MGate MB3000 Modbus Gateway User Manual
Modbus TCP Clients with ASCII and RTU Slaves
Link TCP master devices with both ASCII and RTU serial devices
simultaneously
When integrating Modbus networks, you may encounter different Modbus serial networks that use different
baudrates or a different protocol. Modbus ASCII might be used by some devices, while Modbus RTU is used
by other devices.
The two and four-port MGate models can integrate serial Modbus networks that use different parameters or
protocols. You can configure each serial port to a specific Modbus serial environment; set up a slave ID
table. After configuration, only the gateway will be visible to Modbus TCP clients, and all serial devices will
be integrated behind it.
Serial Master with Serial Slaves over Internet
Let Modbus serial devices communicate over the Internet
Many Modbus devices communicate over RS-485, which limits the number of devices in a network to 32 and
the transmission distance to 1.2 km.
With the MGate MB3000 Modbus gateway, you can link all Modbus devices over an Ethernet network. Up to
32 Modbus gateways can be installed in a single control network, so each device can now be accessed from
anywhere the TCP/IP network can reach.
