tGW-712i Modbus TCP to RTU/ASCII Gateway with PoE and 1-port Isolated RS-232
Compact DIN-rail gateway that links Modbus TCP/UDP hosts to serial Modbus RTU/ASCII devices over Ethernet, with PoE (IEEE 802.3af, Class 1) and an isolated RS-232 port.
- Modbus TCP/UDP master and slave support, bridging to Modbus RTU/ASCII master and slave devices
- Up to 32 TCP connections (masters) per serial port
- 1 x isolated RS-232 port (3000VDC signal isolation) on a male DB-9 connector, with baud rates up to 115200 bps
- Read-cache for faster Modbus TCP/UDP responses and reduced serial bus loading
- PoE (IEEE 802.3af, Class 1) or +12 ~ 48 VDC terminal block power input
- Static IP or DHCP network configuration, with UDP responder for device discovery (UDP Search)

Produktinformation "tGW-712i Modbus TCP to RTU/ASCII Gateway with PoE and 1-port Isolated RS-232"
The tGW-712i bridges Ethernet-based Modbus TCP/UDP masters and legacy serial Modbus RTU/ASCII devices, so serial equipment can be reached over an IP network without the cable length limits of RS-232 connections. It can also pair two serial Modbus devices across TCP/IP, which suits equipment that has no Ethernet capability of its own.
A read-cache stores previous requests and responses in the module's memory. When several masters poll the same slave device with identical requests, the cached reply is returned immediately, which reduces traffic on the serial bus and shortens TCP response times.
The unit can be powered over Ethernet from an IEEE 802.3af, Class 1 PoE switch, or from a +12 ~ 48 VDC supply on the terminal block. Configuration is handled through a built-in HTTP web server, and the order includes a DC-jack to 2-wire power cable, 0.3 M.
