parallel interface cable) used to access information stored in the ROC.
LED Light-Emitting Diode.
Logical Number The point number the ROC and ROC Plus protocols use for I/O point types are based
on a physical input or output with a terminal location; the point numbers for all other
point types are "logical" and are simply numbered in sequence.

the ROC through which local communications are established, typically for
configuration software running on a PC.
LPM Lightning Protection Module; a device that provides lightning and power surge
protection for ROCs.
LRC Longitudinal Redundancy Checking error checking.
M
m Meter.
mA Milliamp(s); one thousandth of an ampere.
MAC Address Media Access Control Address; a hardware address that uniquely identifies each node
of a network.
Manual mode For a ROC, indicates that the I/O scanning has been disabled.
