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.
Wet contact: When the input voltage (i.e. 3-30VDC) between DI and COM more than the threshold voltage, the
point value is 1; when the input voltage (i.e. 1-3VDC) less than the threshold voltage, the point value is 0.
Note: The start register address of DI status is 10200 (0xC8), 2-byte unsigned integer, and the 0x02 function
code is used to read DI status.
3.1.2. DI Data Auto-upload
After checking the "Auto upload data" item in the software tool, it will actively upload the DI status in 4 cases.
• The device is connected to the host computer for the first time
• Any DI channel value of the device changes from 1 to 0
• Any DI channel value of the device changes from 0 to 1
• The device reconnects to the host computer in TCP Client mode after the network is interrupted
3.2. DO Control
3.2.1. DO Status
DO status:
Write 0, COM and NO are open and write 1, COM and NO are close.
Note:
The start register address of DO status is 100 (0x64), 2-byte unsigned integer, and the 0x01 function code is
used to read DO status, 0x05 function code is used to write single DO status, and 0x0F function code is used to
write multiple DO status simultaneously.
3.2.2. DO Power-on Status
It controls DO status when the device is just powered on and has not received the external control command.
After writing 0, COM and NC are on, and after writing 1, COM and NO are on.
3.3. Other Features
3.3.1. 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,
