Bit 6 of the RevPiStatus variable in the process image contains 0 or 1, depending on whether 0V or 24V are applied to the input.
In theory it works like that:

Code: Select all

pi@RevPi:~ $ piTest -r RevPiStatus
1 Byte-Value of RevPiStatus: 1 dez (=01 hex)
1 Byte-Value of RevPiStatus: 65 dez (=41 hex)

Here an example implementation:

Code: Select all

#!/usr/bin/env python3
# CheckConnectInput.py
# Check the digital input pin of RevPi Connect

import revpimodio2
import time

rpi = revpimodio2.RevPiModIO(autorefresh=True)

while True:
	if rpi.io.RevPiStatus.value & (1 << 6):
		print('Hi')
	else:
		print('Lo')
	time.sleep(1)
