Seamless communication between Modbus/TCP hosts and serial Modbus RTU/ASCII devices
The tGW-700 series provides a seamless communication solution between Modbus/TCP hosts and serial Modbus RTU/ASCII devices over an Ethernet network. This eliminates the limitations of traditional serial communication devices in terms of cable length. The gateways offer flexibility in terms of the number and combination of COM ports, and also allow for the optional I/O Pair Connection feature. This feature enables communication between two serial Modbus RTU/ASCII devices via the TCP/IP interface of the gateway.
Improved System Stability and Efficiency with Read-Cache Function
The tGW-700 series stands out with its unique Read-Cache function, which stores previous requests and responses in the module’s memory buffer. This significantly reduces the load on the RS-485 bus, resulting in fast response times. By improving system stability, this feature enables more efficient resource utilization, enhancing overall performance.
tGW-700 Series: Power over Ethernet Support for Increased Efficiency
The tGW-700 (Non-T) series supports Power over Ethernet (PoE) according to IEEE 802.3af (Class 1), allowing the modules to be powered by a PoE switch as a Powered Device (PD). Alternatively, they can be operated using a DC power supply. This series is known for its extremely low power consumption, which contributes to long-term energy efficiency and cost savings for businesses.
tGW-700 Series: Industrial-grade Communication Solutions with Wide Temperature Range
The tGW-700 series is designed specifically for industrial use. It operates at temperatures ranging from -25 to +75°C and has a wide voltage input range of 12 to 48 VDC. Its ability to be mounted on a DIN rail and its compact form factor make it easy to integrate into existing systems.
The tGW-700 series provides engineers and system integrators with a flexible and reliable solution for integrating serial Modbus RTU/ASCII devices into Ethernet networks. With features like the Read-Cache function and Power over Ethernet support, system stability is improved and energy efficiency is increased. The industrial-grade characteristics of the series make it an ideal choice for use in industrial environments.
