Description
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. You could set it up via Web Browser, Serial Console, Telnet Console, Windows Utility or through the LCM display in front of the device. Industrial EMC protection makes MB5916 ready for every mission.
16‑Port Industrial Secure Modbus TCP/RTU/ASCII Gateway with RJ45 connectors, rack‑mount, optional serial port isolation.

Which version do I need?
This page covers the MB5916 gateway. The selection guide's MB5916 row covers the gateway and concentrator functions; the concentrator build is sold as MB5916-CT. The MB5916A and MB5916A-CT are the substation versions: IEC 61850-3 / IEEE 1613, six Ethernet ports (10/100BASE-T(X) or 100BASE-X SFP options), DSub9 or terminal-block serial connectors with 3 kV optional isolation, a 100-370 VDC input option, redundant power and -40°C to +85°C. Choose the MB5916 for periodic polling in a control room, the MB5916-CT for frequent polling by several masters, and an A model for substations.
Typical applications for the MB5916
- Converting sixteen Modbus RTU devices to Modbus TCP from one 1U rack unit
- Control rooms linking serial PLCs, meters and RTUs to a Modbus TCP SCADA
- Utility and plant cabinets with 19-inch racks
- Retrofitting legacy Modbus serial installations without replacing field devices
- Remote access to serial Modbus devices over IPsec VPN or OpenVPN

MB5916 — frequently asked questions
How many ports does the MB5916 have?
Sixteen RS-232/422/485 serial ports on RJ45 connectors and two 10/100BASE-T(X) Ethernet ports with RSTP redundancy, plus one relay output.
How is it configured?
Through a web browser, serial console, Telnet console or ATOP's Windows utility, or directly from the LCM display on the front of the unit.
What is the difference between the MB5916 and the MB5916-CT?
The MB5916 is a gateway: each Modbus TCP request is translated onto the serial line, which ATOP rates as suited to periodic polling. The MB5916-CT concentrator polls the slaves automatically into internal memory so masters get immediate replies, and adds customisable register mapping plus link status and data timestamp access.
What is the difference between the MB5916 and the MB5916A?
The MB5916A is certified to IEC 61850-3 and IEEE 1613, has six Ethernet ports instead of two, DSub9 or terminal-block serial connectors with 3 kV optional isolation, a 100-370 VDC input option, redundant power and a -40°C to +85°C rating. The MB5916 is rated -20°C to +70°C with 2.5 kV optional isolation on RJ45 ports.
What power supply does it need?
ATOP lists 24-48 VDC and 100-240 VAC power inputs. Power redundancy is not listed for the MB5916; choose the MB5916A for redundant power.
What temperature range is it rated for?
-20°C to +70°C operating and -40°C to +85°C storage, in an IP30 rack-mount housing of 440 × 44 × 200 mm.
