5.5 Standard diagnostics with PROFIBUS-DP protocol
Generated alarms are classified and summarized in the PROFIBUS Profile 3.01 and 'Con-
densed status and diagnostic messages' extension.
The diagnostic approach complying with PROFIBUS-DP includes the following types of diag-
nostic transfer:
4
The DP master class 1 reads the diagnosis of the DP slave while the cyclic data exchange
is being set up.
4
In case of an active diagnostic alarm, the slave responds during the data exchange with a
high-prioritized response telegram.
The master requests a diagnosis as a result to continue afterwards with the normal data
exchange.
