... years. With this type, individual or a number of printed circuit
board modules are in a standardised housing.
The hardware design for a programmable logic controller is such that it
is able to withstand ...
This textbook explains the design of a programmable logic controller and
its interaction with peripherals.
One of the main focal points of the textbook deals with the new interna-
tional standard ... very easily realised with contacting compo-
nents. An actuated normally open contact corresponds to a logic 1-
signal and an unactuated one to a logic 0-signal. When working with
contactless components,...
