  SHT20 temperature and humidity sensor with delta dvp12se11t rs485 modbus.

  Hello,

  I’m trying to connect the SHT20 sensor with my DVP12SE11 T PLC in WPLL software with Modbus RTU RS-485 connection to read the temperature and humidity sensor values. Here, I used the sht20 sensor model is MD02, but I wrote the PLC program at that address it’s reading the random values.

  Here I have attached the program.
