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, IEC61850-3 compliance, and wide temperature operation capability render MB5916A ready for every mission.

Advanced embedded security
MB5916A embeds IPsec VPN Encryption, that allows you to tunnel your data securely throught the internet and prevent unauthorized control of your Serial Devices by malicious people.

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.
