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:
