ICP DAS’ tGW-715 tiny Modbus/TCP to RTU/ASCII gateway

ICP Australia has introduced ICP DAS’ tGW-715 tiny Modbus/TCP to RTU/ASCII gateway with PoE and DC jack.

The gateway  enables a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network and eliminates the cable length limitation of legacy serial communication devices.

The module can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel application) and can route data over TCP/IP between two serial Modbus RTU/ASCII devices. This is useful when connecting mainframe computers, servers, or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability.

The tGW-715 features a powerful 32-bit MCU to enable efficient handling of network traffic, and also has a built-in web server that provides an intuitive web management interface that allows users to modify the configuration of the module, including the DHCP/Static IP, the gateway/mask settings and the serial port settings.

This module offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functionality using a standard category 5 Ethernet cable to receive power from a PoE switch such as the NS-205PSE. If there is no PoE switch on site, the module will also accept power input from a DC adapter. The tGW-715 is designed for ultra-low power consumption, reducing hidden costs from increasing fuel and electricity prices, especially when you have many modules installed. Reducing the amount of electricity consumed by choosing energy-efficient equipment can have a positive impact on maintaining a green environment.

Key features include:

  • supports Modbus TCP/UDP master and slave;
  • supports Modbus RTU/ASCII master and slave;
  • max. TCP connections (Masters) per serial port: 32;
  • read-Cache ensures faster Modbus TCP/UDP response;
  • supports UDP responder for device discovery (UDP search);
  • static IP or DHCP network configuration;
  • easy firmware update via the Ethernet (BOOTP, TFTP);
  • tiny web server for configuration (HTTP);
  • Contains a 32-bit MCU that efficiently handles network traffic;
  • 10/100 Base-TX Ethernet, RJ-45 x 1 (auto-negotiating, auto MDI/MDIX, LED indicators);
  • includes redundant power Inputs: PoE (IEEE 802.3af, Class 1) and DC jack;
  • allows automatic RS-485 direction control;
  • 3000 VDC isolation and +/-4 kV ESD protection for i versions;
  • male DB-9 or terminal block connector for easy wiring; and
  • tiny form-factor and low power consumption.
