The A+B- terminal of S04XA is a RS485 communication port. When S04XA is hung behind the host PLC as an extend module, the two terminals do not need any wiring; When the S04XA is used as a remote modul
Haiwell firstly implemented the firmware upgrading function in the small programmable controller,whether it is the host CPU or extension module ,all could be upgraded freely,therefore the old products
H02RS module integrates with two communication ports, while H01RS module only has one communication port, all of Haiwell PLC are expandable to 5 communication ports except E series. Communication exte
1. After H32DT module is power-on, if the channel does not connect with any sensor, the indicator will be off. Connect to the sensor in sequence. Read the temperature value and write them to register
If the actual communication distance is greater than the allowed communication distance of RS485, you can add a relay to extend the RS485 communication distance.
H04DT without RS485 interface can only be hung behind the host PLC for using; H32DT with RS485 interface not only can be hung behind the host PLC as the extend module, but also can be used as a remote
No conflict. The same communication serial port of Haiwell PLC can work with different protocols, because the Haiwell PLC will automatically deal with these problems , there is no need to program.
You can click the menu bar【view/PLC hardware configuration】then open the PLC hardware configuration window,to do some operations like addition and modification for the modules.
