Diagnostics via the I/O diagnostics interface (STI)

The CPX terminal provides a bus-independent 16-bit I/O diagnostic interface - provided the controller
has the appropriate hardware configuration. This interface enables access to internal data of the CPX
terminal, which enables internal parameters and data to be read out at the I/O level.

9.5

Diagnostics via CPX-MMI

The operator unit CPX-MMI enables a menu-driven display of diagnostic information. Errors can be
read out locally in plain text.

9.6

Diagnostics via CPX-FMT

The Festo Maintenance Tool (FMT) offers PC-based diagnostic functions via a graphical representation
of the CPX terminal, e.g. status display, parameterisation.

Diagnostics via PROFINET

PROFINET forms the basis for comprehensive diagnostic functions and information via the automation
network, e.g. detailed module-related and channel-related status information and error detection in
the online mode of the control software.
Error characteristics
In the case of the following malfunctions the behaviour of the CPX terminal depends on the configured
behaviour of the controller and the parameterised fail-safe setting:
– Telegram failure
– Stop the controller
– Network interruption
The fail-safe parameterisation is used to specify the signal status of the outputs in the event of
fieldbus communication errors in the network. This signal state is called fail-safe state.
