When checking I/O devices, it is important to also check the wiring associated with the device. Input devices, such as photo eyes, may change states when being blocked or unblocked, but this might not be sensed by the machine controls due to faulty wiring or a bad connection.
To check I/O devices, follow these steps:
1) | On the HMI Main Screen, tap the Equipment Modules button |
2) | Tap the desired Equipment Module button |
4) | Tap the Inputs & Outputs button |
5) | Watch the color of the circle next to the device name while someone else flags the device |
6) | Verify the state changes as this is done |
a) | The circle next to the device name will be green when its input is energized |
