Basic functions: support standard MODBUS devices such as text, touchscreen, PLC, etc.
The 16 way analog output (support 4~20mA, 0~5V, 0~10V) 16 way 10bit output, the accuracy is 0.1%.
1 channel standard 485 communication port (support modbus-RTU protocol)
Code function support function code:
Function code definition operation (binary)
0x03
0x04 reads register data and reads data from one or more registers.
0x06 writes single path registers, and writes a group of binary data to a single register.
0x10 writes multiple registers to write multiple sets of binary data to multiple registers.
********************************************
MODBUS address: default is 1, configurable
Baud rate: default is 9600, configurable
8 Bit data bits
1 bit stop position
No check
40001~40016 16 road analog output
**********************************************
Analog input and output VC source code, which is clear, and can also provide Delphi source.

UInt16 readBUF (byte ip_Addr, UInt16 data_Addr)
{
UInt16 CRC, / / check value
Byte[] MSG = new byte[8], / / instruction array
Msg[0] = ip_Addr, / / from the machine.
Msg[1] = 0x04, / / read a single register
Msg[2] = (byte) (data_Addr > 8), / / high register address
Msg[3] = data_Addr (byte), / / low register address
Msg[4] = 0x00, / / the length of the data to be read high
Msg[5] = 0x01, / / read length of the data base
CRC = CRC16 (MSG, 6), / / CRC
Msg[6] = (byte) (CRC > 8), / / check 8
Msg[7] = CRC (byte), / / check low 8
Comm.Write (MSG), / / read request to send frames
(receive_A_Frame), / / return signal receiving frame
/ / add here: judging the received data
