System Defined Inputs and Blocking Spindle Run

Sort of a two part question
a) Input, when using the config app, you can choose from some predefined input functions.
Is there anywhere were these are full documented in how they interact with the system
eg SpindleOK, SpindleUnlock, ToolIsClamped
b) I am ordering spindle that has the ability to change tool, I think Franco reviewed it.
The user manual advises a few things....
i) air supply for "air seal" be kept running when ever the spindle operates.
So i have an air pressure switch ( NO when below target PSI ) on the air supply.
ii) That the spindle is not operated if the "tool-clamp" indicated not clamped.
(It is not clear if this sensor can internally block the spindle for spinning up.)
So how then to use these two inputs to ensure the spindle can not run if they are active.
SpindleOk - kicks you out of MDI when active, even if the spindle is not running.

I'm not suggesting there is a fault or anything.
Just curious to learn the details of these pre-defined inputs.
If i define an input as "SpindleOK", and I am in MDI mode, and this triggers it shows a "Spindle Error" and reverts to the main screen.
That's fine - makes sense.
But give the Spindle's tool holder has 2 outputs (outputs a voltage, not a relay/pull low/OpenCollector)
I'd like to ensure the spindle can not run if these are not in their correct states.

Below is a list of all the Inputs, without trying each of them, some have some defined behavior when they trigger.
Is this documented anywhere ?

• ChuckIsOpen
• ChunkIsClosed
• CutOffIsDown
• DriveOk
• EStop
• FirstAxisHomeOk
• FirstAxisMinusLimitOk
• FirstAxisPlusLimitOk
• SecondAxisHomeOk
• SecondAxisMinusLimitOk
• SecondAxisPlusLimitOk
• ThirdAxisMinusLimitOk
• ThirdPlusLimitOk
• ThridAxisHomeOk
• FourthAxisHomeOk
• FourthAxisMinusLimitOk
• FourthAxisPlusLimitOk
• HomeAll
• LimitAll
• LubeOk
• PartChuteIsIn
• ProbeDetect
• ProbeTripped
• SlaveHomeInput
• SpindleHighRange
• SpindleIsLocked
• SpindleIsOriented
• SpindleLowRange
• SpindleMedRange
• SpindleOk
• ToolIsUnclamped
• ToolTouchOffDetect

So, dunno about the existing variables for Acorn, as i'm using OAK's, but this is pretty easy to do directly in the PLC code
The code looks like this:
;--Air pressure for ATC
IF (M3 && !AirPressureOkay)
THEN FaultMsg_W = AIR_PRESSURE_LOW_FAULT, SET OtherFault_M
; Spindle must have a tool to be allowed to spin
IF (M3 && SpindleColletOpen)
THEN FaultMsg_W = COLLET_OPEN_FAULT, SET SpindleFault_M
IF (M3 && !SpindleToolPresent)
THEN FaultMsg_W = TOOL_NOT_PRESENT_FAULT, SET SpindleFault_M
(I defined these fault messages)
To avoid the MDI issue you mention, they only trigger if M3 is set.
I defined AirPressureOkay, SpindleColletOpen, and SpindleToolPresent inputs, and they come directly from the spindle sensors/air pressure trigger sensor.
It looks like Keith just posted Acorn PLC programs for ATC here, including Rack mode ATC

I'll give those a read.
Thanks
