I have a twelve year old VIPA 100 series PLC running my home automation (came with the house).
The HMI is from COPDATA Zenon 6.22 to a VIPA CE Touchpad.
The system runs the interior and exterior lights, dimming and automation of lights, room temperature sensors affecting radiator and underfloor heating actuators, irrigation, garage door opener and few other things I’m sure. It does work but the HMI is clearly dated.
I have separate central alarm system with various motion sensors and cameras also. And also a separate fire and smoke alarm system.
The VIPA CPU has a Siemens UPS and there is also an EREA 24v power supply.
These are the VIPA components;
1 x CPU 214 NET
16 x 8 Digital Output 230v/5A
1 x 16 Digital Output 24v 2A
1 x 8 Digital Output 24v 1A
1 x 8 Digital Input 24v
1 x Profi Bus DP Master IM208 DP
1 x Modbus TCP slave Module, IM253 NET running Siemens S5 Protocol
1 x 4-port switch CM240
Would it be possible to build an more open system to replace the VPIA PLC using the Controllino hardware and openPLC to support a more modern Home Automation service and HMI like openHAB or Home Assistant using MQTT or similar?
Or would it be more practical to start from scratch?
Any thoughts would be welcomed.
