Hello,
I am getting down to designing the installation in my house.
The project involves using a Satel Integra 128 control panel and a PLC - S7-1200.
I know that practically most of the assumptions could be realised with SATEL alone, but due to my professional deviation I want to use a PLC. Additionally, it will be easier for me to build a web interface to manage the whole thing externally.
Assumptions:
- automatic switching of lighting when entering rooms,
- closing of roller blinds when the alarm system is activated,
- automatic switching off the air-conditioning when nobody is in the room,
- external lighting control
and much more.
Wiring assumptions:
- each light switch 2xUTP (bistable relay control, temperature sensor).
- each socket 3x2.5mm2 + 1xUTP cable (NC monostable relays will be flush mounted).
- UTP in any place assuming the need for control now or in the future (gas cooker, fireplace, awning on the garden, garage door etc.).
The design is roughly done (I'll brag about it when I'm finished). I have set about working out the logic and establishing the output inputs on the Satel and PLC and have encountered one problem - connecting the PIR detectors to the PLC.
Namely - the SATEL outputs are all low current OpenColector type, the inputs on the PLC are 24V voltage.
I have no idea at this time how to transfer the status of the detectors between SATEL and the PLC.
What solution do you recommend?
