The tGW-700/GW-2200i module is a Modbus gateway that enables a Modbus TCP/UDP 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 then route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting computers, servers or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability. The maximum number of TCP connections for each serial port is up to 32(RevB), this allows multiple masters accessing slave devices on the same serial port. The read-cache function is used to store previous requests and responses in the memory buffer of the tGW-700/GW-2200i module. When other HMI/SCADA master controllers send the same requests to the same RTU slave device, the cached response is returned immediately.This feature dramatically reduces the loading on the serial port communication, ensures faster TCP responses, and improves the stability of the entire system. The GW-2200i series has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easier and total costs of cable and switch are signifi cantly reduced. LAN Bypass feature guarantees the Ethernet communication if GW-2200i loses its power.
 
The tGW-700/GW-2200i module off ers true IEEE 802.3afcompliant (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-700/GW-2200i module is designed for ultra-low power consumption, reducing hidden costs from increasing fuel and electricity prices,especially when you have a large number of modules installed. Reducing the amount of electricity consumed by choosing energy-effi cient equipment can have a positive impact on maintaining a green environment.
Based on an amazing tiny form-factor, the tGW-700/GW-2200i achieves maximum space savings that allows it to be easily installed anywhere, even directly embedded into a machine. It also supports automatic RS-485 direction control when sending and receiving data, thereby improving the stability of the RS-485 communication.
