services
The standardized service "Get_Attribute_Single" (Service Code 0x0E) returns a data
stream with the maximum data length (attribute 2) when instance attribute 1 is accessed.
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 a manufacturer-specific service. In this ser-
vice, the telegram structure for the request and response are the same. The telegram
contains routing 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 vari-
able.
The following table shows the complete telegram structure.
