3.4 Request for event data
The event date, combined in 2 words, contain all error messages and alarms of the equipment.
They can be called up via short set to identify a special error.
This request can be made asynchronous, for example, if the service request bit (collected errors) was set before in any random response telegram in
the function field (FF).
Example: Equipment address = 5
See 2.4.2.2 for contents of the function field (FF)
The 4 characters of the event data block are bit fields which are combined to form the error status words 1 and 2.
These 4 characters can also be read by data request with parameter index 21h.
See the operating instructions for more explanations and information on error elimination.
