Connecting the inverter to the fieldbus
Where can I find instructions for the fieldbus connection of the inverter?
Instructions for connecting to a fieldbus can be downloaded from the Internet:
● Application examples (http://support.automation.siemens.com/WW/view/en/60733299)
● Operating Instructions: CU230P-2 operating instructions
(https://support.industry.siemens.com/cs/ww/en/view/109478827)
● "Fieldbuses" function manual: Manuals for the Control Unit
(http://support.automation.siemens.com/WW/view/en/30563628/133300)
Description files for fieldbuses
The description files are electronic device data sheets which contain all the required
information of a higher-level controller. You can configure and operate the inverter on a
fieldbus with the appropriate description file.
Generic Station Description for PROFIBUS: GSD
(http://support.automation.siemens.com/WW/view/en/23450835)
GSD Markup Language for PROFINET: GSDML
(http://support.automation.siemens.com/WW/view/en/26641490)
Ethernet/IP: EDS (http://support.automation.siemens.com/WW/view/en/78026217)
BACnet MS/TP: PICS
eu.org/uploads/tx_teproddb/catalog_pdf/PICS_CU230P-2_HVAC_v46_HF.docx)
Alternative for the download for GSD and GSDML
GSD and GSDML are saved in the inverter. If you insert a memory card in the inverter and
set p0804 = 12, then the inverter writes the GSD or the GSDML to the memory card. You
can then transfer the file to your programming device or PC using the memory card.
