I would like to connect a button/switch to RevPi MIO module. How to wire it properly?

Great idea, you can start by this helpful knowledge base article that guides you wring and commissioning: Commissioning RevPi MIO
And have a look at this video tutorial where we connect a button to a DIO Module - just adapt the steps according to your MIO Module. Tutorial 12 – Digital IO Modules application example

This is helpful. I need additional help with understanding wiring.
# toggle RevPi MIO digital output 1
import revpimodio2
import time
rpi = revimodio2.RevPiModIO(autorefresh=True)
OutputValue=True
while True
rpi.io.DigitalOutput_1.value=OutputValue
time.sleep(0.5)
OutputValue = not OutputValue

Hi curious-eng, sorry I forgot to answer your question as I did not have a button around but an LED.
EDIT: However, you have to be aware that your circuit will not work like that. Use 24V between the switch and input 1. So like this:
[24V] - [Switch] - [Input 1]
Open PiCtory and configure the variable of the MIO module "IO_Mode_1" as digital input.
Then save the PiCtory configuration.
The value 1/0 should reflect the circuit state closed/opened of your button.

Hi, I’d like to add a momentary button in order to trigger a shutdown of the module. Following the information in this thread, does the image below look like it’s wired correctly?

Hello ptthomps, if you have a hardware revision 1.2 then yes, otherwise no. See excerpt from datasheet:
