00001 to 09999 are discrete outputs (coils)
10001 to 19999 are discrete inputs (contacts)
30001 to 39999 are input registers (usually analog inputs)
40001 to 49999 are holding registers
All Modbus addresses are based on 1; i.e. the first data value starting at address 1, the effective address range depends on the slave device, different slave devices supporting different data types and address ranges.
The communication method for realizing the Modbus by Java comprises the following steps:
v/obtaining all communication ports in the system
portList＝CommPortIdentifier.getPortIdentifiers()；
V/compare if the serial name is the designated serial
paramConfig.getSerialNumber().equals(commPortId.getName())
// open (application name [ optional nomenclature ], number of milliseconds to wait while blocked)
serialPort＝(SerialPort)commPortId.open(Object.class.getSimpleName()，2000)；
// set up serial port monitoring
serialPort.addEventListener(this)；
// set serial data time valid (monitor)
serialPort.notifyOnDataAvailable(true)；

byte[]readBuffer＝new byte[inputStream.available()]；
Furthermore, the previous application is only simple real-time monitoring, the system simultaneously saves data points in a historical database after acquiring real-time points, and a user can check the industrial control state at a certain historical moment, so that the system has great application value in the investigation and analysis of accident reasons in industrial control application. For example, the history reproduction of the screen is monitored, and by selecting a specified time of the history, it is possible to view the reproduction of the history screen state from that time.
Aiming at the current situation of a coal conveying program control system of a thermal power plant, the field control mostly adopts the PLC to carry out equipment control, most of the PLCs expand the serial port communication mode, and the national requirements on information safety are also met. The Java-based serial communication can automatically set the communication frequency, and carry out rapid data interaction under the condition of permission of equipment conditions.
In addition, the data points of the monitoring picture are directly acquired through a Mobus protocol, so that the intermediate step of a real-time database is omitted, the communication is more efficient, meanwhile, the dependence on third-party software is avoided, and a whole set of autonomous monitoring solution can be provided.
