PROFINET IO process communication
The PROFIdrive profile specifies telegrams used for process communication. The VACON
drive supports four types of different telegrams with and without extra process data items. These
telegrams contain either PROFIdrive or VACON
The following chapters describe the different types of telegrams and the signals that form them.
5.3.1
Telegram types
The telegrams defined in the chapters below use different combinations of control and reference
values. Control and status word can be either VACON
Speed reference and actual values can use different scaling.
Please check details of telegrams before taking them in use.
5.3.1.1
Standard Telegram 1 and variants
Standard Telegram 1 types are used, when a standard VACON
functionality is required. These telegrams (table below) use PROFIdrive-defined control word,
status word, speed setpoint value and speed actual value. When using these telegrams, the process
data fields are communicated as 16-bit values. STW1 will force edge sensitive run control.
