3.1.1 Optical interface
Description
The ET 200pro FC frequency converter has a serial optical communication interface with
USS protocol for commissioning using the STARTER commissioning software on a PC.
RS232/optical conversion is performed in the cable between the PC and the frequency
converter.
The following components are required:
● PC with Windows 2000/Windows 2003 Server/Windows XP
● STARTER commissioning software (version 4.1 or higher)
● RS232 interface cable (Order No. 6RK1 922-2PB00).
3.1.2 Fieldbus interface (backplane bus)
Description
Communication between an ET 200pro station and the associated higher-level control
(e.g. SIMATIC S7) is established using the standardized PROFIBUS DP communication
protocol or PROFINET I/O. Communication within the ET 200pro system is performed over
the ET 200pro backplane bus. The ET 200pro IM 154 interface module creates the interface
between the two bus systems.
Communication data
The ET 200pro FC frequency converter is operated and controlled in normal process mode
via PROFIdrive profile 4.0 with standard telegram 1.
The PROFIdrive profile with the standard telegram 1 provides the following functionality:
● Sending control words and setpoints with a fixed length to the drive
● Receiving status words and actual values with a fixed length from the drive
● Indicating drive faults through data record 47
● Reading/writing parameters via data set 47.
Note
Parameter values are transferred in acyclic data exchange through data record 47.
Standard diagnostics
The frequency converter can be included in the standard diagnostics of S7.
