The Industrial Raspberry Pi Forum

Hi, I would like to build a solution where we use 4 AIO modules. As I've read already we need two Revpicore.
Each of them has possibility to connect max two AIO modules becaouse one PiBridge could handle one AIO module on end of the chain.

Am I right ?

Or maybe there is a posibility to use onlu one Revpicore ?

If not the last question: each Revpicore has its own separate OS? Or You have OS/Application to connect two Revpicore in one ecosystem?

Thank for help

Hi Piotr Włoda, the short answer is yes you can connect four AIO modules to a RevPi Core 3/+ or RevPi Connect/+ Module.
Have a look at this post for the explanation about the PiBridge modules combinations possible:

If you want to interchange data you have Ethernet, ModbusTCP, etc. available.
Have a look at this made with love video tutorials #20 and #22 about ModbusTCP Master and Slave

Have a look a the RevPiModIO and the RevPiNetIO libraries which are also community proven to speed up your development
https://revpimodio.org/en/doc2/net/
If you need support for those libraries please answer them in this board here "RevPiModIO" as this are community supported 3rd part components.

Hi dirk,

Hi Piotr Włoda, the short answer is yes you can connect four AIO modules to a RevPi Core 3...

do You mean a single RevPi Core 3 ?

And finally this is our requirement (based on Analog I/O and Digital I/O we need):

Is this possible on one single RevPi Core 3 ?

Hi yes this is possible with a single RevPi Core 3/+ Module.
Yes, this configuration from the picture will work.

OK thanks for Your support
