Cmax Parameters And Cpx Node Parameters - Festo CPX Series Manual

1. CPX terminal configuration and FHPP overview

1.1.2 CMAX parameters and CPX node parameters

1−4
The CMAX has a number of specific parameters. These inter
nal CMAX parameters cannot be stored as module para
meters in the CPX node, but are exclusively saved in the
CMAX.
It is therefore not possible to access to the CMAX parameters
in the usual way via the I/O diagnostic interface or via any
corresponding bus−specific channels, but only via special
functions.
Note
For CPX terminals with the CMAX, when exchanging the
CPX terminal or the CMAX, it is always necessary to carry
out parametrisation and commissioning again, since the
parameters and data determined during commissioning
are only saved in the CMAX.
The internal CMAX parameters can be changed with the fol
lowing functions:
Festo Configuration Tool with CMAX plug−in
Cyclical fieldbus communication with the control
and status data of the FHPP (parametrising mode).
See sections 2.2.6 and 6.2.
Acyclical fieldbus communication (e.g. PROFIBUS DPV1).
See section 6.3 as well as the respective supplementary
description in Appendix C.
