Type: addressed Parameters: card, channel, address, identity, option Each Orbit Module is given a unique 10 byte identity (ID) during manufacture. When used on a network it is more efficient to use a shorter temporary ADDRESS stored in the Orbit Module memory;...
  • Page 16 DIOM 502237_Issue 2.qxd 20/07/2005 15:38 Page 14 3.0: Communication with the DIOM Orbit Command OrbitRead1 Description: returns the state of the DIOM inputs. Type: addressed Parameters: card, channel, address, reading The 8 least significant bits of the returned 16-bit number show the state of the input pins. Each pin must first be set high (via OrbitPreset) if it is to be used as an input.

Switch bounce. Noisy Supplies. Mechanical vibration. If a port is being used to read a switch condition for example, a single OrbitRead1 may have missed the event or may have seen a noise spike in the place of the event.
