4.2.1 Parameter types
The parameters are preset at the factory. These pre−settings
can be used for a large number of applications. With the aid
of parametrising, the characteristics of the CPX terminal or
the characteristics of the individual modules and I/O chan
nels can be adapted to each particular application.
The possibilities available depend on the
fieldbus protocol
used. Information about this can be found in the manual for
your CPX bus node.
A distinction is made between the following types of para
meters:
Types of
parameters
Description
System parameters Influence the behaviour of the complete
CPX terminal
Module parameters
 module−specific
Influence the behaviour of a particular
module
 channel−specific Influence the behaviour of a particular input
or output channel
Diagnostic memory
parameters
Influence the working method of the internal
diagnostic memory
Tab.4/1: Types of parameters
The individual parameters are described in detail in Appendix
B.2. Basic principles of using the parameters can be found in
Appendix C. The tables below give a brief overview of the
most impor tant parameters.
