Hi Timelord,
the 209se gateway isn`t cheap, I know.
But an other option: easy control CPU EC4P222 + XION ECOmoduls
Ethernet, canopen/easynet, webserver 12/8 I/O are included. Codesys 2.3 programming system.
Here`s CPU price higher ~600€ +140€ can gateway + I/O (16DI~75€, 16DO~85€, 8AI~200€)
OK, check the prices and see ...
I'll check that one as well , THX.
I've tried out now and simulated some 15 different PLC and brands, I'm getting quite tired ( and experienced
)
Nice HVAC system integrated in a fridge
Got a new one now with 4 compressors , you noticed 2 extra compressors on top ?
That's only only half of the System ,the other half with evaporator freq. regulated mainmotor and hydroponics is in the hall partially in the ceiling.
Woking on this prototype since years .
Now I need a PLC to optimise the savings. ( 3-4 Mw yearly extra with standard Airco
)
The production unit will be indoors integrated in a fridge.
One of the pictures shows an LOGO! program. Do you have actually Logo! controller in use? The new Logo! 0BA7 has ethernet include.
No it's not the Siemens Logo!, I tested that one too, it gave me not enough I/O , No , it's xLogic (Chinese)
Now Easy 800 has enough I/O and even with Remote I/O via NET.
Maybe I go for the Easy800 with the 209 .... it's bearable.
With remote I/O is even better then for my configuration (half the system outside),
with xLogic I have high costs for cabling , subrelays and termination.( only transistor output, but that one WORKS great)
I'll test your idea, THX a lot,
