Note!

For a multi-parameter request, correct and faulty messages, if any, are combined

in one telegram. The individual messages have the following data contents:
• Correct message

– Format: 0x40
– Number of values: 0x00

• Faulty message

– Format: 0x44
– Number of values: 0x01 or 0x02
– Error code without additional information (number of values = 0x01) or
– Error code with additional information (number of values = 0x02)

Faulty access to a parameter "n" will be reported in the response message of a

multi-parameter request at position n.
