MGate protocol gateways serve as critical translators between diverse industrial communication protocols, enabling smooth interoperability and enhancing SCADA system efficiency. The advanced MGate MB3x70-G2 Series further improves system responsiveness through its Agent ModeActive Polling: Agent Mode continuously polls data in the background and instantly delivers cached information to SCADA systems, eliminating the latency associated with conventional transparent gateways.. It also seamlessly integrates nonstandard serial devices into Ethernet networks without complex programming, thanks to its built-in proprietary serialNo PLC Programming: Allows almost any custom serial equipment to be connected to Ethernet networks without rewriting PLC programs, simplifying industrial integration. capabilities.

This illustration demonstrates how the MGate Series acts as a seamless bridge between serial-based field devices and Ethernet-enabled SCADA or HMI systems. By converting Protocol A from field equipment into Protocol B for supervisory systems, the gateway ensures reliable, low-latency communication across industrial networks. This solution enables engineers and system integrators to integrate diverse assets without modifying existing PLC programs, improving operational efficiency and network interoperability.

Migration Path: From G1 to G2

Rethinking the Connector Layout

For older gateways, everyday maintenance challenges are often less about performance and more about cabinet accessibility. On G1 units, the DB9 serial connectors are positioned along the bottom edge, which can create inconvenient cable routing and limit working space after the unit is mounted. With G2, the serial connections are relocated to the front face and provided as terminal blocks, making wiring, cable testing, and cable replacement easier without removing the unit from the rail.

• Front-facing terminal blocks provide easy access for wiring and cable checks without dismounting the unit
• The 4-port DIN-rail model provides more connections within the same panel space
• Simplified cable management helps reduce maintenance time and shorten maintenance windows

One Interface Your Team Already Knows

Hardware upgrades can come with an overlooked cost: retraining the engineering team. G2 minimizes that disruption by retaining the familiar menu logic used on G1 while reorganizing it into clearer top-level sections for the dashboard, protocol status, network and serial settings, security, account management, and diagnostics. G1 configuration files can also be imported directly into a new G2 unit, allowing teams to migrate devices without rebuilding their configuration from the ground up.

• Familiar workflow presented through a cleaner, more organized menu structure
• Field teams can get started without requiring a dedicated training cycle
• Direct import of G1 configuration files reduces setup and migration time
• New role-based permissions allow administrators to control which settings each login can modify
• Built-in diagnostics eliminate the need for a separate monitoring utility

Evaluating the Upgrade

• G1 hardware is built on an older platform that is nearing end of life
• G2 introduces current-generation components with a stronger baseline security posture
• Typical street pricing is comparable to, or lower than, the current cost of G1
• With the familiar interface carried forward, teams avoid additional re-certification and training overhead

The table below highlights the key differences between G2 and G1 across hardware, protocol support, EMC rating, security posture, network design, and diagnostics.

Where MGate G2 Fits in Industrial Applications

• Oil & gas sites: connecting serial flow meters and RTUs to a centralized SCADA network in environments requiring ATEX/IECEx ratings
• Substations: integrating serial protection relays with Modbus- or EtherNet/IP-based monitoring platforms
• Water treatment plants: migrating legacy serial PLCs and meters to an Ethernet backbone without modifying the existing control logic
• Mixed-vendor production lines: consolidating PLCs and drives using different protocols, including PROFINET and EtherNet/IP, onto a unified network
