Compiler A compiler is a program that translates the source code of a
program into the strings understandable to the target computer.

On-Board Denotes as much as permanently installed “on the CPU
motherboard”.
Parse A parser is a program which, in computer engineering, is
responsible for the decomposition and conversion of any input
(text, e.g. AWL) into a format useful for further processing.
PCD3.M6xxx x in the product description stands for a number 0...9. In this
case, it is an additional three-digit number, e.g. PCD3.M6560.
PGU Programmable Unit
PLC Process Logic Controller
Port Interface description
PWM PWM stands for Pulse Width Modulation. Pulse width modulation
works with a constant pulse rate and a constant pulse amplitude,
only the pulse width is variable. Because the pulse rate is
constant, but the pulse width changes, the pulse duty factor
changes.
With a PWM output, it is possible to output analog values without
expensive A / D converters
