General information

CPX terminals are delivered in mounted form. For extension or conversion, remounting may be neces-
sary:
– Dismounting or remounting of the manifold block when exchanging the connection technology
– Dismounting and remounting of the electronics module by setting the DIL switches or exchanging
the electronics module

Meaning
Output
Modular electrical terminal which is particularly suitable for use in the pro-
cess industry (intrinsically safe electronics modules available)
Input
Highway Addressable Remote Transducer
Bidirectional, platform-independent data transfer protocol that permits
access to the data of intelligent field devices
Process image of inputs
Process image of outputs
The process image is part of a controller's system memory. At the start of
the cyclical program, the signal states of the input modules are transferred
to the process image for the inputs (PII). At the end of the cyclical program,
the process image for the outputs (PIO) is transferred to the output mod-
ules as a signal status.
