3. Product Features
3.1. DI Data Acquisition
3.1.1. DI Type
Dry contact: Short DI and GND, the point value is 1; otherwise the point value is 0.
Note: The start register address of DI status is 10100, 2-byte unsigned integer, and the 0x02 function code is
used to read DI status.
3.2. Other Features
3.2.1. DI Pulse Mode
• Positive/negative pulse state
Indicate the current input pulse status. When the DI is open, the positive pulse status register value is set to 1.
When short the DI and GND, the negative pulse register value is set to 1. Writing 0 will clear the detected pulse
state and writing other values is invalid.
• Positive/negative pulse count
Indicate the number of positive/negative pulse changes. The initial value can be written. After writing, it can be
counted from the initial value to the maximum value of 65535, and then it can be re-counted from 0.
• Logic level count
Indicate the sum of the number of positive/negative pulse changes. The initial value can be written. After writing,
it can be counted from the initial value to the maximum value of 65535, and then it can be re-counted from 0.
3.2.2. Filter Parameters
The DI signal must be kept for several sampling periods before it can be confirmed. The default value is 0x6, which
means that 6 sample periods are required to be confirmed. This value can be modified according to the site
conditions, and the range is 0-20.
3.2.3. Zeroing
When set to auto-zero, the DI positive/negative pulse count or DI logic level count value will be automatically
cleared after each reading.
When set to manually clear, DI positive/negative pulse count and DI logic level count value will not be cleared
every time, and need to be cleared manually. (Manually write the value 0 to clear)

· DI Value: Short DI and GND, value is 1; otherwise, the value is 0
· DI Positive/Negative pulse count: Number of pulse changes, readable and writable. When DI Automatic
zeroing is set to "Automatic", the pulse count will be clear automatically after each reading. When DI Automatic
zeroing is set to "Manual", the pulse count will not be clear after each reading (the maximum value is 65535 and
then reset to zero), which needs to be manually cleared (manually write value 0 to clear).
4.2.3. Control Device Status
The software can change the state of the device by changing the point value.
