Diagnostics at the CPX terminal

4.5.1 Status bits in the system status of the CPX terminal

Festo CPX-CM-HPP-EN 2017-06b English
Malfunctions of the connected axes are reported as CPX error
group to the CPX master (CPX bus node or
CPX-FEC/CPX-CEC). One diagnostic channel is thereby
available for each drive Tab. 4/9. The following sections
include the special features of the representation for the
CPX-specific diagnostics options.
– Status bits (see Section 4.5.1)
– Diagnostic memory with CPX error groups
(I/O diagnostics interface, see Section 4.5.2)
A CPX-CM-HPP error is always specified in the system status
of the CPX terminal as follows:
Module type in which an error has occurred:
– Bit 0 - 2 = 0
– Bit 3 = 1:
Error in analogue/function or technology module
Error type
– Bit 4 - 6 = 0
– Bit 7 = 1: Other error
Further notes on the structure of the status bits can be found
in the CPX system description (CPX-SYS-...).
