Can I overlap a momentary pushbutton with a multi-state indicator?
I want to be able to use a single pushbutton to send a bit to the PLC, let the PLC decide what is the appropriate state for the device and send a display value (integer) to the multi-state indicator.
There will be five states, "Not Selected", "SELECTED" "RUNNING FWD" "RUNNING REV" and "INHIBITED".
I don't want to use a multi-state pushbutton because the PLC will use a lot of other variables to control which state the device displays.
When the system is in MANUAL MODE, the operator will be able to toggle between "Not Selected" and "SELECTED" by touching the button for each conveyor which are laid out graphically to visually match the equipment.
At the bottom of the screen, there are SELECT NONE and SELECT ALL buttons which will affect the state of all of the conveyors. There are also JOG FWD and JOG REV buttons, so the operator can select multiple conveyors and jog them all at once.
Any time a conveyor is moving, the indicator will show the direction, even when the system is running in automatic.
If other factors prevent the motor from being jogged, the INHIBITED state will be displayed when she/he attempts to jog.
I have created one with the momentary PB hidden behind the multi-state indicator, and validated the application without any errors, but I don't want to go test it and find out it won't work correctly.
If the button is hidden behind the indicator, will it still work?
I have about 16 more of them to create in this fashion, but it would be nice to know if I am doing this right before I proceed.
Thanks,
Paul
