Overview
The Moxa MGate 5103 is a 1-port industrial Ethernet gateway that converts Modbus RTU/ASCII/TCP or EtherNet/IP to PROFINET IO device communications. It bridges existing Modbus and EtherNet/IP field devices onto PROFINET-based control systems — such as Siemens or other PROFINET PLCs — without replacing existing field infrastructure.
Key Features
- Protocol conversion: Modbus RTU/ASCII/TCP or EtherNet/IP → PROFINET IO device
- Supports Modbus RTU/ASCII master/slave and Modbus TCP client/server
- Supports EtherNet/IP Adapter mode
- Effortless web-based Quick Setup wizard with GSDML export for PROFINET PLC configuration
- Built-in Ethernet cascading (2 x 10/100BaseT(X) RJ45) for simplified wiring
- microSD card slot (up to 32 GB) for configuration backup/duplication and event logs
- Modbus RTU/ASCII/TCP Protocol Traffic Monitor for installation-stage troubleshooting
- Status monitoring and fault protection with relay output alarm
- Redundant dual DC power inputs (12–48 VDC) via Euroblock terminal
- 2 kV built-in serial port isolation
- HTTPS (TLS 1.3), SNMPv3, AES-256 security
- ATEX, IECEx, Class I Division 2 hazardous location certification
- Wide-temperature model (-T) available: -40 to 75°C
- 5-year warranty
Protocol Details
The serial port (DB9 male, RS-232/422/485, 50 bps–921.6 kbps) supports Modbus RTU/ASCII master and slave modes. Modbus TCP operates as client and server with up to 16 client and 32 server connections. PROFINET IO device supports 1 IO controller connection with 512 bytes input/output. EtherNet/IP Adapter supports 1 scanner connection (read-only) and 1 scanner connection (read/write) with 496 bytes input/output. Supported Modbus functions: 1, 2, 3, 4, 5, 6, 15, 16, 23.
