 Note!
In the case of a multi-parameter request, correct and possible faulty messages are
summarised in one frame. They 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)
A faulty access to a parameter "n" is indicated at the nth position in the response frame
of a multi-parameter request.
