4 bit-Code use M581

[Stan 0]

When using the M581 trigger command, is it possible to use several IO connectors as input?
I like to implement a 4-bit code with 16 triggers by using just 4 IO Connectors on the Duet 6Hc.

@stan-0 you can only 'or' inputs together, not 'and' them which is what you are looking for. If a slow response time (e.g. 1 second) was acceptable, you could use daemon.g to poll the 4 inputs instead.

Yes this is what I am loking for.
Is there any opportunity to implement something like a 4 bit Code in the Firmware?
I need 15 trigger and just have the 4 IO Connectors left.

What about the bitmapping feature of M670
Is it any good for this usecase?

@o_lampe M670 just set the IO-Port on and off. I like to set IO's from an SPS and use them to Control the board.
@dc42 Which command I need to poll the inputs in daemon.g?
