GT-540
|
The GT-540 is an intelligent Active GPRS Remote Terminal Unit. Within the high performance 32 bit CPU, the GT-540 is suit for the hard industrial environment. It features GPRS/GSM module, 6 digital inputs, 2 digital outputs, 1 analog input, 2 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 by 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, the GT-540 offers the e-mail mode to transfer the data by e-mail via GPRS for users to choose. The simple I/O linkage function of the GT-540 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, the GT-540 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 GPRS and the Internet.

Utiliy
Software Solutions
The M2M RTU center software with friendly Graphic interface is to manage the GPRS RTU products easily. Users can monitor the I/O data and status of GPRS RTU devise by the interface on PC. By using the GPRS 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.
Easy to Establish GPRS Network Applications
It is a big headache for engineers to establish the GPRS applications because the dynamic IP management is required. Applying the GT-540 and M2M RTU center software, the dynamic IP addresses can be managed between them. The remote GPRS RTU product would connect to M2M RTU Center automatically. Therefore, all remote GPRS RTU devices can be managed by s single centralized M2M GPRS RTU Center software with a fixed IP address. Moreover, there are M2M API tool and OPC server for engineers to develop the GPRS applications by VB, VC or SCADA development tools conveniently without any IP address management effort.
Active data transmission
The GT-540 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.
Transfer data by e-mail
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 GPRS in the fixed time.
Modbus RTU device connectivity
The GT-540 is built-in Modbus RTU protocol. That can make any Modbus RTU device connect to the GT-540. By the way of GT-540, Modbus RTU devices can be used in GPRS remote system. The max Modbus RTU device can be connected to the GT-540 is three.
Simple Local I/O link Control
There are I/O built-in GPRS RTU devices of ICP DAS. Therefore, these products can be the 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.
Built-in I/O Data Logging
The GT-540 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.
