DTE
Data Terminal Equipment
EMI
Electromagnetic interference.
embedded I/O
Embedded I/O is the controller’s on-board I/O. For MicroLogix
controllers, embedded I/O is all I/O residing at slot 0.
expansion I/O
Expansion I/O is I/O that is connected to the controller via a bus or cable.
MicroLogix 1100, 1200 and 1400 controllers use Bulletin 1762 expansion I/
O. MicroLogix 1500 controllers use Bulletin 1769 expansion I/O. For
MicroLogix controllers, embedded I/O is all I/O residing at slot 1 and
higher.
encoder
A device that detects position, and transmits a signal representing that
position.
executing mode
