Is the folder name necessary?

Remove unnecessary spaces before =

Align =

Align =.

Align =.

We don't have to align =, but if you're going to have all of these spaces before the =, you should align.

Why are we doing this?
Having a return here is against our coding standards (it's like a goto).

Consider separating the wait for door close to another state.

Should not change states in a signal function. Should set a request flag that gets looked at in dry self-tests state handler function which would return install state if the flag is set.

Remove blank line.

Move this transition function call to the transitionToPostTreatmentMode function below.

Invalid payload length shouldn't be a reject reason, it should cause a s/w fault (because it suggests the UI and TD software are not compatible versions).

Not necessary

This command should be given once on way out of prior state instead of every 50ms while in this state.
We also need to zero the timer counter at same time so the timeout check below works.

Response needs to be sent immediately (in message handler function). This is too late.

We shouldn't need to do this door check if you've required door be closed for the state.
Call the doorClosedRequired( TRUE ) function on transition into a state that requires the door to be closed and call with ( FALSE ) on transition into a state that doesn't require door to be closed. When required = TRUE, the switch monitor will trigger the door open alarm for you.

Remove extra blank line.

Not necessary if you give retract command on way out of prior state.

I don't think this if statement is necessary. We wouldn't be in this state if the ejector didn't extend already.
I think we just want to see if BP is home again (completed 1 revolution) so we know when to stop and go to next state.

Give ejector retract command and zero timer counter here too.

Not needed if you do this on way out of prior state.

Start BP and zero timer counter here.

Not necessary if fault property of alarm is TRUE.

Not necessary if you do this on way out of prior state.

Remove ejector homed stuff. Not needed.

Give eject cmd and zero timer counter here.
