The standardized service "Get_Attribute_Single" (Service Code 0x0E) delivers a data
stream with the maximum data length (attribute 2) when instance attribute 1 is ac-
cessed. The data content is filled with zeros. If a data stream is added to the request
telegram ("Service Type Custom"), this data is returned in a mirrored form (Vardata
test mode).
The Vardata service (service code 0x32) is manufacturer-specific. Request and re-
sponse of this service have the same telegram structure. The telegram contains rout-
ing information, the data length of the Vardata user data telegram and the actual
Vardata layer -7 telegram. The data length of the Vardata layer -7 telegram is variable.
The following table shows the complete telegram structure.
