The error instances of the I-ports are assigned standard to the
outputs. If no outputs are intended in the configuration of the
CTEL master module, the error instances are assigned to the
inputs.
In the CPX terminal, the individual modules also have priorit-
isation. This runs from the CPX fieldbus master (always com-
pletely to the left) descending to the right. Modules that are
closer to the fieldbus master thus have a higher priority than
modules sitting further to the right.
Within a CPX terminal, diagnostics/error messages with refer-
ence to inputs have priority over diagnostics/error messages
of outputs. This principle of error prioritisation also finds use
in the CTEL master module in the I/O mixed operation.
Tab. 4/3 shows an overview of the CPX errors as well as pos-
sible causes and information for error handling.
