5、 Communication instructions for intelligent isolation multi-channel voltage and current collector

(1)This instrument can be equipped with RS232 and RS485 interfaces for direct communication with a computer. The RS485 standard communication distance is 1.5km, and multiple instruments can be attached. The RS232 standard communication distance is 15m, and only one instrument can be attached. The TXD, RXD, and GND of the RS232 interface are respectively connected to the second, third, and fifth pins of the computer serial port. The data format consists of 1 start bit, 8 data bits, no checksum, and 1 stop bit. To avoid communication conflicts, the instruments are all in listening mode. The computer sends a command to a certain instrument at a specified address, and then waits for a period of time for the instrument to respond. After the instrument receives the correct command, it sends out the data. After sending, the instrument is in listening mode again. In the same system, instrument addresses cannot be the same, and baud rates must be consistent.

(2)The instrument adopts the standard Modbus rtu communication protocol. When using the configuration software, the device to be selected is a Modicon (* Kang) PLC, Modbus RTU address type, with function numbers of 3X or 4X, and data of integer 16 bits. The Kingview software register starts from 0001 or 0000 (i.e. 4X001, 4X000), while other configuration software may start from 3x001 or 3x000. The communication is an integer, and users need to handle the decimal places according to the actual situation. Communication transmission data is signed integer data, and it is recommended to define signed integer data for user programming. When the data is greater than 0X8000, the actual negative value is obtained by adding 1 in reverse. For example, if the communication transmission data is 0XFFFF, the corresponding data value is -1. For long integer data such as cumulants, the data value is equal to the high-order x 65536+low order. During configuration, users can also choose the data type as long, and the system will automatically calculate the cumulative amount.Register correspondence table (please refer to the setting section of the operating instructions for specific meanings)
