3500/22M 146031-01 Remote Bidirectional Communication

3500/22M 146031-01’s on-site monitoring point is automatically controlled by PLC and relevant information is collected, which is connected to GSM DTU terminal through RS232 or RS485 interface, and the equipment information collected by PLC is sent to GSM wireless network through GSM DTU terminal after data processing and protocol encapsulation.

The monitoring centre of 3500/22M 146031-01 adopts the public network access scheme Server adopts the public network method to access the Internet, such as ADSL dial-up/telecom dedicated broadband Internet access, etc., and applies for the fixed IP address of the public network; small and medium-capacity system applications can be achieved. The server adopts the DDN line provided by the provincial mobile communication company, applies for the configuration of fixed IP address, and connects with the GSM SMS remote control module. As the DDN line can provide higher bandwidth, when the number of PLC on site increases, the centre can meet the demand without capacity expansion, and it can realize the application of high-capacity system.
