EDS file
The EDS file for RETA-01 and DCS550 is available. Please ask Your local ABB agent for the newest one
concerning the current DCS550 firmware.
Mechanical and electrical installation
If not already done so insert RETA-01 into slot 1 of the drive.
Drive configuration
Activate the Ethernet adapter by means of CommModule (98.02). Please note that the DCS550 works with the
instances 102 / 103, if Protocol (51.16) is set to 2 (Ethernet/IP ABB Drives communication profile). The
instances 100 / 101, 20 / 70 and 21 / 71 are also supported, if Protocol (51.16) is set to 1 (Ethernet/IP AC/DC
communication profile). With these instances, it is not possible to use the full flexibility of the DCS550. For
more information, see User’s Manual.
Parameter setting example using Ethernet/IP ABB Drives communication profile
