Help with Eaton easy-E4-UC-12RC1

Good afternoon everyone,
I don't know if you can help me but I have a problem where I am using an eaton easy-E4-UC-12RC1 plc and I have simply programmed it so that when a box passes the photocell it triggers an electrovalve. But when I pass a box through the photocell, it doesn't activate the solenoid valve. If you could help me, I'd really appreciate it.
The programming I have is I01--------()Q01.

Which model of photocell are you using? And is that a PSU top left?

Are you sure you can connect photocell directly to the input? You can use multi-meter on I1 to check if the triggering level is reached while changing light level on the photocell.

After writing a bunch of hardware "try this", I'm opting for a simple programming idea; use the input to set a variable and the variable to drive the output. PLC's read inputs, run the logic (ladder) and write outputs. You may need the internal variable to bridge from read to write.

Lopez47. You’re concept is correct but I agree with kmikemoo and phoenixcomm. Are you sure the photocell is sending a signal? That the PLC can read? Is the solenoid getting the voltage it requires?
