4.2 Service Data Objects
In this chapter you will find a description of all Service Data Objects
(SDOs) used.
The manufacturer specific Service Data Objects serve for the trans-
mission of control parameters to and from the web guiding control-
ler and for the setting of operating and guiding modes. Moreover,
the Service Data Objects can be used for querying status messages
and operating states of the web guiding controller. Each Service
Data Object consists of a transmit and a receive message.
4.2.1 Service Data Objects Overview
The following table provides an overview of all Service Data
Objects used in protocol 3100. A detailed description of the
different Service Data Objects can be found in the chapter Object
Descriptions, page 29.
The abbreviations in the Access table column have the following
meanings:
ro = read-only (read-only access)
rw = read & write (read and write access)
