Product-specific terms and abbreviations
The following product-specific abbreviations are used in this
description:
Term/abbreviation Significance
ATEX zone Potentially explosive area
Bus nodes Establish the connection to specific buses. Transmit control signals to the
connected modules and monitor their ability to function.
CP Compact Performance
CPX bus Data bus via which the CPX modules communicate with each other and
are supplied with the necessary operating voltage.
CPX-EA modules Collective term for CPX modules which provide inputs and outputs and
which can be integrated in a CPX terminal.
CPX terminal variant P,
CPX terminal (-P) Modular electrical terminal which is particularly suitable for use in the
process industry (intrinsically safe electronics modules available).
CPX-P modules Collective term for modules that have been developed specifically for
variant P CPX terminals.
DIL switches Dual-in-line switches consist of several switch elements with which set-
tings can be made.
I Input
I/O modules Collective term for the CPX modules which provide inputs and outputs
(CPX input modules and CPX output modules).
I/Os Inputs and outputs
I module CPX input module
Interlinking block Lower part of the housing of a module or block for interlinking the module
electrically with the terminal.
Intrinsically safe circuits Circuits which release so little energy during operation, or in the event of
certain faults under specified test conditions, that no ignition can occur in
a particular potentially explosive atmosphere.
Mechanically actuated
contacts A mechanically actuated contact features a resistor that is connected in
parallel to the contact. This thereby prevents a wire break signal in the
event of an open contact.
