Diagnostic and error messages

Malfunctions or errors are sent to the bus module as an error number and can be evaluated by the net-
work or suitable Festo software.
The prerequisite for sending diagnostic/error messages (if supported by the network) is an existing
connection to the host system and a corresponding parameterisation of the module
è 3 Parameterisation.
2.3.2

Priorities of the diagnostic/error messages

The module differentiates various instances that can cause diagnostic/error messages. These
instances have various priorities in the automation system CPX-E.
If several diagnostic/error messages cannot be sent in parallel on the network side, the error message
with the highest priority is displayed.

• The error instances of the ports are allocated to the outputs by default.
• The prioritisation of the individual modules in the automation system CPX-E runs to the right in
descending order from the bus module (position always far left).
• Diagnostic/error messages from inputs have priority over diagnostic/error messages from out-
puts.
