Oct. 25+ LMS Passive sensors and IEC61499 adaptors

Should IEC61499 adaptors be used /taught? 
Using:
  • LMS passive sensors 
    • raw value read = 0-1023, but FB interface output variables might return:
      • raw value
      • extracted value like True or False
  • All LMS Sensors
Commonality:
  • All Sensors:
    • INIT event:
      • reserves PORT# to the first sensor FB type
  • Passive Sensor Read Value
    • Sensor value read internally is always 0-1023
    • 0 if no sensor is plugged in
    • If FB says its touch sensor, but light sensor plugged no way to flag as an error
