1.1 Module power supply Haiwell temperature and humidity module can be the expansion module for any host PLC; When the module is directly hung behind the host PLC by parallel bus, no need to take external power supply, the module is powered by host PLC’ parallel port, if the power supply of module is insufficient (the PWR power indicator does not light), then according to different models, the module can be powered by 24VDC or 220VAC.
= 3456, that is the actual value of 345.6 ℃. As we know that Haiwell temperature and humidity modules can be set the signal type of each channel arbitrarily, so for the H04RC module, after configuration, we can read the temperature value directly when connecting the corresponding sensor to the channel.
Module used as remote IO Haiwell PLC expansion module is built-in one RS485 communication port(Some models with Ethernet communication port), which not only supports parallel bus(Use the expansion bus to connect with the parallel interface of host PLC), but also supports serial...

Haiwell PLC - Temperature & Humidity Module Application Case If there is only one machine connected with 485 line, then check "stand-alone search"; if there are more than one, then remove the button of "stand-alone search", and set the start address and end address, so that all the machines connected with 485 line can be found and achieve parameter configuration.
Haiwell PLC - Temperature & Humidity Module Application Case After setting, select the "Download parameter" to download the parameter into the module. In addition, we can do the following operations through the remote module tool: Online monitor the channel value of module, error code.
1.8 Remote IO appliciation example: Haiwell Cloud configuration communicates directly with H08TC module 1, Open Haiwell SCADA software, select the "new project", choose to add the device in the "device", then choose serial port or Ethernet according to the module which supports the Ethernet or RS485, this example for serial port, the serial port number of USB to 485 is COM12, as shown below: Default parameter 19200 N 8 2 RTU for the module, station number address is 1.
CR14 ~ 17, it indicates the humidity value of channel 1 ~ 4 when the channel is selected as a temperature and humidity sensor, so we can read humidity value through the FROM instruction, in this case, H04DT is the first module near the host PLC, so Slot = 1.
Haiwell PLC - Temperature & Humidity Module Application Case 1.10 H32DT module usage features introduction H32DT supports sensor signal types: DS18B20, RW1820, DS1990. Module parameters: H32DT module has 2 channels, each channel can measure the maximum 16 points of temperature, a total of 32 temperature points can be measured.
