ZL-5xType analog signal transmitter supports MODBUS-RTU function code 03 and two 06 kinds of function code.
For example, channel 1 of the channel 1 analog output, that is, write the register 4x0000, the order is as follows:
01 | 06 | 0001 | 01 F4 | D8 1D |
Equipment number | Write function | Register address | Register value | check |
Among them, the set of analog data is 1388, that is, 0x1388, decimal number is 5000, then the output value of I=5000/1000 = 5; 84 9C is 16 Decimal value,
CRC-16 (BISYNCH, polynomial is x16 + x15 + x2 + 1 shield word for 0A001H)
Cyclic redundancy algorithm is obtained. Please refer to the MODBUS for further information about the algorithm.
The returned data should be:
01 | 06 | 0001 | 01 F4 | D8 1D |
Equipment number | Write function | Register address | Register value | check |
lRead register --03
Read 2 device channel 1 and channel 2 of the current input value, 0x0005, 0x0006 two Register commands are as follows:
02 | 03 | 0005 | 0002 | D4 39 |
Equipment number | Read function | Register address | Register number | check |
Return data:
02 | 03 | 04 | 013202 2A | E9 BF |
Equipment number | Read function | Number of bytes | data | check |
Among them, the channel 0132 is the value of 1 0x0132, decimal number is 306, then the input value is 306/1000 = 0.306, the same calculation method,
Can calculate the channel 2 input values.
