5 Manufacturer specific encoder classes
With manufacturer specific encoder classes P+F 2.1 and P+F 2.2, the rotary encoder
offers, in addition to functions based on the encoder profile of the PROFIBUS user
organisation, functions such as commissioning mode (TEACH-IN), speed output and
limit switches.
The following table describes transfer of individual parameters in the parameter
assignment telegram. Note also the following: Users will generally be using user-
friendly input masks in the projecting tool. The structure of the parameter assignment
telegram itself is only of interest in exceptional cases.
