Communication Description:
Read the First Voltage Input (AD1 Input 1V Voltage):
Host Sending: 01/04/0000/0001/31CA/
Station number/function code/first address/quantity/check code/
Module Return: 01/04/02/0064/B8DB/
Station number/function code/bytes/voltage data/check code/
Read 1 to 16 Channels Of Voltage Input (16 Channels Of AD input 1V voltage):
Host Send: 01/04/0000/0010/F1 C6/
Station number/function code/first address/quantity/check code/
Module Return: 01/04/20/0064006400640064006400640064006400640064

Modify Module Parameters (baud Rate, Station Number):
- The baud rate and station number parameters of this module are stored in the data register, which can be modified by command
- Modification Of The Baud Rate: Write data (00H~08H corresponding to 9 baud rates) into the module data register 19H (the address corresponding to the baud rate) to modify the baud rate. After the module responds, the baud rate Will be modified, this parameter can be saved after power-off.
The Corresponding Relationship of These 9 Baud Rates is:
00H 600 01H 1200 02H 2400 03H 4800 04H 9600 (default) 05H 19200 06H 38400 07H 57600 08H 115200
Example: Modify the current baud rate to 1200bps
Host Sends: 01 06 00 19 00 01 99 CD
Module Returns: 01 06 00 19 00 01 99 CD
- Modification of the Station Number: Write data (00H is the broadcast address, 01H is the default address of the module) to the module data register 18H (the address corresponding to the station number) to modify the station number. After the module responds, the station number will be changed. Modify, this parameter can be saved after power-off.
Example: Modify the module whose current station number is 01H to 09H
Host Sends: 01 06 00 18 00 09 C9 CB
Module Returns: 01 06 00 18 00 09 C9 CB
Module returns When the baud rate and station number information is forgotten, you can reset by shorting the TP1 pad on the module to ground (use with caution)
Features:
1The acquisition module uses a highaccuracy AD chip, 16channel analog voltage input, with stable operation. 2The input range of analog quantity acquisition is 0-10V, the accuracy can reach 0.02V, and the data acquisition is fast and accurate. 3The initial baud rate is 9600 and the station number is 01, and the baud rate and station number can be adjusted by instructions. 4Use wireless communication to transmit data, which is convenient and safe to use and avoid measurement errors caused by connection. 5Can be networked with PLC, HMI, PC, etc., and is widely used for signal control of industrial field equipment.
