GT-540-3GWA
|
GT-540-3GWA is an intelligent Active 3G Remote Terminal Unit. Within the high performance 32 bit CPU, GT-540-3GWA is suit for the hard industrial environment. It features 3G(WCDMA) module, 6 digital inputs, 2 digital outputs, 1 analog input, 1 RS-232, 1 RS-485 and SD interface. It can be used in M2M application fields to transfer the local I/O or Modbus device’s data via GPRS by the defined period or DI/AI triggers. The local I/O data can also be stored in the SD card to become a remote data logger. For another communication path, GT-540-3GWA offers the e-mail mode to transfer the data by e-mail via 3G for users to choose. The simple I/O linkage function of GT-540-3GWA can reach the real time control in local field. It also supports Li-ion battery as another power source when the main power is failed temporarily. Therefore, GT-540-3GWA is an ideal solution for environmental monitoring and remote device management for M2M applications. Meanwhile, it is supplied with easy-to-use API and OPC server Software that streamline application development process, freeing system integrators from dealing with complex communication protocols of 3G and the Internet.

The M2M RTU center software with friendly Graphic interface is to manage the WCDMA/GPRS RTU products easily. Users can monitor the I/O data and status of WCDMA/GPRS RTU devise by the interface on PC. By using the M2M RTU API tool and M2M RTU center software, any remote monitoring system can be achieved easily and efficiently. For SCADA system, the M2M.OPC server is provided to connect to SCADA by OPC interface.
It is a big headache for engineers to establish the WCDMA/GPRS applications because the dynamic IP management is required. Applying GT-540-3GWA and M2M RTU center software, the dynamic IP addresses can be managed between them. The remote WCDMA/GPRS RTU product would connect to M2M RTU Center automatically. Therefore, all remote WCDMA/GPRS RTU devices can be managed by s single centralized M2M RTU Center software with a fixed IP address. Moreover, there are M2M API tool and OPC server for engineers to develop the WCDMA/GPRS applications by VB, VC or SCADA development tools conveniently without any IP address management effort.
GT-540-3GWA with active I/O transmission mechanism can raise the communication. Unlike the traditional poll communication, it would transfer the data by the defined time, DI trigger or AI hi/lo alarm. In addition to improve the way of communication, that can also reduce the AP effort.
Expect for the transferring data by the general communication with the M2M RTU center, users can choose the e-mail mode to send these data by e-mail over WCDMA/GPRS in the fixed time.
GT-540-3GWA is built-in Modbus RTU protocol. That can make any Modbus RTU device connect to GT-540-3GWA. By the way of GT-540-3GWA, Modbus RTU devices can be used in WCDMA/GPRS remote system. The max Modbus RTU device can be connected to GT-540-3GWA is three.
There are I/O built-in WCDMA/GPRS devices of ICP DAS. Therefore, these products can be the WCDMA/GPRS I/O devices. Expect for these local I/O data can be sent to the host PC, the I/O link function of them help users to do the simple control in local field. For example: the DI trigger or high/low AI alarm can driver the DO channel.
GT-540-3GWA provides an external SD interface. These local I/O and Modbus data are recorded in SD memory card for one day in a single file.
