The Schneider EGX100MG is a PowerLogic EGX100 Ethernet Gateway used to connect power monitoring devices and other compatible serial communication equipment to an Ethernet network. It provides a communication path between field-level metering equipment and Ethernet-based supervisory systems.
The gateway is particularly useful in electrical distribution systems where multiple meters or monitoring devices communicate over a serial network while the plant or building management system operates over Ethernet. By bridging these communication layers, the EGX100MG allows existing metering infrastructure to be accessed from a networked monitoring environment.
A typical installation places the EGX100MG between a serial device network and an Ethernet infrastructure. Connected meters can exchange data through the gateway, while supervisory software or a monitoring workstation communicates with the gateway over the Ethernet network.
For commissioning and maintenance, the communication path should be checked from the Ethernet side through the gateway to the connected serial devices. Network configuration, serial communication parameters, device addressing, and wiring all affect successful data exchange.

The EGX100MG acts as a communication bridge rather than a measurement or control device. It receives data from compatible serial devices and makes that information available through the Ethernet communication network.
Power Meters / Serial Devices → EGX100MG → Ethernet Network → Monitoring Software / SCADA
When a supervisory system requests information from a connected meter, the request travels through the Ethernet network to the EGX100MG. The gateway handles the communication between the Ethernet side and the serial device network, allowing the appropriate field device to respond.
The reverse path is also used when device information is transmitted toward the monitoring system. Metering data such as electrical measurements and operating status can therefore be collected centrally without requiring each field device to have a direct Ethernet connection.
The EGX100MG occupies the communication gateway layer between electrical metering equipment and the Ethernet network. It separates the field communication network from the higher-level monitoring infrastructure while allowing data to pass between them.

The EGX100MG is used as a communication gateway between compatible serial-connected devices and an Ethernet network. It allows supervisory systems to access data from connected power meters and monitoring equipment.
No. The gateway handles communication rather than electrical measurement. Measurement values originate from connected meters or monitoring devices and are transferred through the gateway to the higher-level system.
Check the meter’s address, serial wiring, communication parameters, and device status first. If other meters remain accessible, the fault can often be isolated to the affected device or its local communication path rather than the Ethernet gateway.
The Ethernet network configuration, serial device settings, connected meter addresses, and monitoring-system communication should be verified after replacement. A complete communication test should confirm that the supervisory system can again access the required field devices.
