Response to a read error
In the case of a mul-parameter request, correct and possible faulty messages are summar-
ised in one telegram. They have the following data contents:
Correct message
•
Format: data type of the value requested
•
Number of values: as described above.
•
Parameter value: value requested
Faulty message
•
Format: 0x44
•
Number of values: 0x01 or 0x02
•
Error code without addional informaon (for number of values = 0x01) or error code with
addional informaon (for number of values = 0x02)
A faulty access to a parameter "n" is indicated at the nth posion in the response telegram of
a mul-parameter request.
