The entry door on an office floor needs to be able to be opened by the secretary if needed. But from a PC! Monitoring is needed to determine whether the door was opened and whether someone is waiting in the hallway If someone enters the hallway, the lights need to be automatically turned on and then off again after an appropriate time.
The solution might look like this
Door opener, relay with lighting control, buzzer button, solenoid switch and motion detector are connected to the Web-IO.
A Web page is created which allows operation of door opener and lights.
All this functions without any cabling, since the Web-IO is simply connected to the existing network.
1. A door opener and a relay for controlling the lights are connected to a Web-IO. A buzzer button, a solenoid switch and a motion detector are connected to the inputs of a Web-IO.
2. The Web-IO was connected to an available Ethernet port and supplied with power.
3. An IP address was assigned to the Web-IO.
4. A HTML page was created for signaling when the doorbell button is pressed and having a button for opening the door and a button for switching the light on/off. It was even possible to display the video image of the observation camera on the webpage.
In addition to eliminating new cabling, one of the benefits of this solution is that the Web page can be opened from any PC in the company. If the secretary is not at her desk, the door can also be opened from another location.
Of course, it is also possible to switch a barrier or any other actuator using the Web-IO.
