I am building myself a bungalow and am in the process of connecting my own home automation.
The original plan was to run the alarm on an Integra 32/64, connect a PLC to it via RS/IP and use it to control relays (lights, sockets, ...). When setting up the alarm, after a discussion with the installer, he convinced me that it was not worth buying an external PLC, but a larger Integra and to implement everything there. Whether this was a good choice is a different topic; in any case, there is an Integra 256, installation in full star topology, 210 field distribution cabinet, 24U RACK cabinet (among other things, for twisted-pair extension in LSA) and I am starting to buy actuators.
I can easily connect everything via monostable relays (Wago 788-303 / 788-304 rather than Relpol RM85), but this is continuous relay operation. Seemingly under 0.5W, but that's 0.5W x 50-80 relays. So I've been looking for bistable relays, the ideal example is the Relpol RM851, just no idea (I have little experience with Integra) how to implement / program this.
RM851 changes its state depending on the polarity of the coil inputs: passing a pulse (I think 50ms is enough already) in +- polarity switches the contacts on, with -+ pulse disconnects them.
I have some ideas on how to do this current wise:
- to control the relays, install an H-bridge circuit (or suitably connected 2 relays), and on the Integra something like: if you want to switch on, control the output with a relay, if you want to switch off, first control the output of the H-bridge, and then the output with a relay
- use +12V and -12V from the ATX power supply, so instead of the H-bridge give the switching relay, Integra as above
But:
1. is it possible to do something like this in the Integra?
2. relays for polarity control must first disconnect +12 and only then switch on -12 (or there +12 and 0)
3. on the INT-O you have to use relays and not OC outputs (difficult, overall less power consumption anyway)
I'm not interested in solutions like "if it's supposed to be switched on for less than 12h then connect it to the NC outputs" because I don't want to let the power go out to keep something switched off.
The Internet is generally silent on the subject: the discussion immediately shifts to "you can take such a monostable" or "bistable output in Integra". In general, finding a bistable relay has been a problem.
I am interested in a discussion on how to implement this on the Integra/how much effort is needed to implement it on the Integra, also compared to normal PLCs.

It would be simpler to map the outputs in the Integra and with the Integra (after IP in ETHM-1) read the states, only for this a separate controller, i.e. simpler to have a separate PLC
