Diagnostics

Function
The positioner can report active information about its device status. These diagnoses are
important information that can be used by an automation system to initiate remedial measures.
Standard mechanisms of PROFIBUS-DP are used to transfer the diagnostics information and
report it actively to the class 1 master. PROFIBUS-DP has a protocol to transfer the information
that has higher priority than the useful data to the class 1 master.
