change of state in field device cause action in Outsystems

  
Hello all,

If I have a device in the field, in this case a card reader on a door, and I want to have an action happen in my Outsystems platform immediately (or less than 15 minutes which appears to be the minimum time for a timer, how can I do it?  Lets say it reads the card #, sees if the associated user has access to that door and if so it will reply to a PLC based system to unlock the door and log this entrance.

Via Rui's expert help we got the RFID (now available on forge) working however that does require the card reader to be plugged into a pc.  This example is using a PLC in the field which doesn't exactly have a comm port, just tags inside it.  So lets abstract it a bit and just say a device in the field which has data points and which I can read via actions.  Any thoughts on how to make a change in state in a field device automatically initiate an action in the Outsystems platform?
