Diverse Hardware
Infrastructure
Modbus Gateway supports the four most commonly used communication standards,
RS-232/485/422, and Ethernet. The ease-of use configuration utility provided
with Modbus Gateway can quickly select the hardware interface , and
easily switch to the existing communication infrastructure. Industrial EMC
protection and wide temperature operation capability make MB5904D ready for
every mission. And if cabling is an issue, the PoE-powered version can allow
MB5904D to be powered through PoE.
Advanced embedded security
and advanced features
Relax. MB5904D Modbus Gateway supports OpenVPN and IPsec VPN encryption,
allowing you to safely use the device over the internet without worrying about
malicious attacks, data sniffing or unintentional remote control of your Modbus
slaves. On your LAN, RSTP protocol will provide an additional layer of security
in case of link losses.
Switching between Modbus
Protocols
Modbus Gateway supports the standard Modbus protocol and is capable of
converting any Modbus protocols between Modbus TCP, Modbus RTU, and Modbus
ASCII for all supported hardware interfaces. All of this, in bidirectional
mode: Ethernet and Serial ends can selected to be either master or slave Modbus
ID Routing. Modbus Gateway supports various types of hardware communication
interfaces, Modbus protocol conversion, and Modbus ID routing. Therefore the
Modbus Gateway can integrate your existing and complex Modbus hardware
configuration into a simple network that can be easily managed.
