Series Description

A compact and rugged 4G Modbus Gateway
Based on ATOP’s Industrial-grade hardware, the MB5901B Series is a cost-effective Modbus Gateway for seamless conversion between Ethernet-based Modbus TCP and serial-based Modbus RTU/ASCII for demanding applications such as Industry 4.0 and Smart Grids. Its rugged, reliable hardware features high EMC protection, wide temperature operation, and programming and installation flexibility in one device, while its advanced performance protects your data over the Internet with secure IPsec VPN or OpenVPN tunnels, with its powerful CPU providing up to 37.9Mbps* software-assisted AES encryption.

Flexibility
In addition to offering installation flexibility, the MB5901B series’ configuration options enable it to be set up over Ethernet via Telnet, Web Browser, Serial Console, or our Windows Utility.

Maintenance 4.0
ATOP Virtual COM software provides a virtual environment for applications when accessing MB5901B through TCP. Special management via SMS can be performed, such as polling data, issuing commands and system reboots.

Added value
A dedicated I/O version provides 2 x digital inputs and outputs each. These are also accessible via dedicated Modbus Registers. The -B version model also provides 15 seconds of back-up power in the event of a power failure, allowing the device to relay the failure to the host.
