Communication ConnectionThe instrument provides asynchronous h

2、alf-duplex RS485 communication interface wich adopts MODBUS-RTU protocol so all kinds of data can be transmitted on the communication line. Theoretically, one communication line can be connected with up to 128 instruments, each of which can set a communication address (Addr) and communication rate (

3、baud) via setting.For the communication connection, we recommend to use the three-core shielding wire .The core wires are connected to A,B,COM2 respectively and the shielding layer is connected to the ground. COM2 is forbidden to have ground connection. When laying the wires, the communication line

4、shall be kept away from the strong current cable or other strong electric field.It is recommended to add a matching resistor between A and B of the end instruments. The resistance range is 120。lOkQ.See 7.6 for specific connection case.7.1 Transmitting MethodThe information transmission is asynchrono

5、us and in bytes. The communication message tranmitted from the master to the slave is in 1 O-bit format including 1 start bit,8 data bit(LSB first delivered),no parity bit, one stop bit. If parity bit or 2 stop bit is et, the format is 11-bit.7.21 nformation Frame FormatAddress codeFunction codeData

6、 zoneCRC check code1 byte1 byten byte(s)2 bytesAddress code: the address code is in the beginning of the frame, which is composed of a byte (8 bit binary code)representing 0255 in decimal system. The PZ instrument only uses 1 247 and keeps other addresses. The bits indicate the address of the termin

7、al device designated by the user. The device will receive the data from the linked master. The address of every terminal device must be unique. Only the end addressed will correspond to the query containing its address. When the terminal sends back a response, the responding slave address will tell

8、the master which terminal is communicating with it.Function code: the function code tells the addressed termnial to carry out which functions. The table below lists up the function codes used by this instrument as well as their meanings and funcitons.FunctionDefinitionOperation03H/04HData reading re

9、gisterObtaining the current binary value of one or more registers.10HPreset multi-registerSet the binary value into a series of multi-registerData zone: the data zone contains the data needed for carrying out certain functions or collected when the terminal responds to the query. The content of the

10、data may be number, reference address or set value. For example: if the function code tells the terminal to read a register,the data zone needs to specifiy which register to start with and how much data to be read. The embedded address and data will vary with types and different content of the slave

11、s.CRC check code:CRC field occupies two bytes including one 16-bit binary value. The CRC value is calculated by the transmitting devicie then added to the data frame. The receiving device will recalculate the CRC value upon receiving the data then compare it with the received value in the CRC field.

12、 If the two values are not identical, there is an error.The procedure to generate a CRC”A.Preset a 16-bit register as OFFFFH (full 1), which is called CRC register.B.Make XOR calculation with 8 bit of the first byte in the data frame and the lower byte in the CRC register and store the result into t

13、he CRC register.C.Shift the CRC register right a bit and fill the MSB with 0 and take out the LSB for checking.D.If the LSB is 0, repeat step 3 (one more shift); if the LSB is 1, m,ake XOR calculation with CRC register and preset fixed value (0A001H).E.Repeat step three and step four until the 8th s

14、hift. The entire 8 bit processing is complete in this way.F.Repeat step two to five to process the next 8 bits until all bytes are processed.GFinally, the CRC register value becomes the CRC value.Besides, there is also a wayt to calculate CRC using the preset table. It is characterized by rapid calc

15、ulation speed. However, the table needs relatively large storage room. We will not introduce it here, please refer to relevant materials.7.3 Function Code IntroductionFunction Code 03H or 04H: Reading RegisterThe function allows the user to obtain the data collected and recorded by the device and sy

16、stem parameters. The data number requested by the master computer for one time has no limitation but cannot exceed the defined address range.The following examples are 3 basic data read from 01 slave computer (every address in the data frame takes up 2 bytes):UAB, UBC, UCA. Among them, UABs address
