www.haiwell.com 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.
Click to exit, enter the configuration interface, as shown below:
We can change the module name, address, IP, subnet mask, baud rate, data format and other communication parameters in
the communication parameter area.
In the external analog input area, we can set the signal type of each channel, choose whether to use engineering value or
not((for temperature module, the default use of engineering value)), the upper and lower limits of engineering value(it can be
set if you check the use of engineering value), sampling times and zero correction.
