The Industrial Raspberry Pi Forum

I am using the revpi connect with codesys.
I can control led A2 trough the revpiled byte as expected ( red & green ).
However A1, A3 and the relay on X2 only give a short pulse on the rising edge signal of the according revpiled bit.

In codesys the bit stays in the condition i set it at and forcing it does not change the behavior.

signal :___,-----,__,-----,____
led :___I______I_______
relay :___I______I_______

i would like to use the relay on the X2 for shutdown indication so correct behavior is important.

What would be causing this behavior?

Hello,

we are not familiar with this behaviour. I have just tried this with our latest image and it all worked.
I have tried this with codesys and piTest.

Please follow the checklists below.

I hope this will solve your problem.
