3.4 System network structure
3.4.1 System schematic diagram
3.4.2 The physical structure of the system: The system composes a three-tier C/S structure through the local area network, database management, and controller system, and the hardware communication connection mode is optional. The communication between the main controller and the PC can only adopt the RS232 protocol communication, and the communication with the controller is RS485.
3.4.2.1 The communication server is directly connected to the controller solution configuration
-When the communication distance between the communication server and the controller is less than 10 meters and there is only one controller, use RS232 protocol to communicate, using direct serial port connection or multi-serial port card connection;
-When the communication distance exceeds 12M, it does not exceed 1200M, and when there is no local area network in the communication area, RS422 communication can be used. If there is a LAN network interface or the management client and hardware equipment are in different buildings or far apart, it can be used Network converter connection, equipment such as MOXA DE-311, DIGI one sp.
-When the communication distance exceeds 12M and does not exceed 1200M meters, if there is no network setup, the MODEM remote dial-up communication method is adopted.
3.4.2.2 The communication server is directly connected to the main controller solution configuration
-When the communication distance between the communication server and the main controller is less than 10 meters, use RS232 protocol to communicate, using direct serial port connection or multi-serial port card connection;
-When the communication distance exceeds 12M, there is a local area network in the communication area, which can be connected by a network converter, such as MOXA DE-311, DIGI one sp. The network converter can also communicate with different connection modes of RS232 and RS485/422, the communication distance is different, please refer to the previous point;
-When the communication distance exceeds 12 meters, if there is no network setup, the MODEM remote dial-up communication method is adopted.
-Note: This solution suggests to use direct serial communication as much as possible. Communication through a network converter will be affected by the local network environment. The use of MODEM dial-up communication speed is also a problem, especially in a real-time monitoring system, it may be difficult to achieve the expected results.
