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
Modbus/TCP, if Protocol (51.16) is set to 0 (Modbus/TCP).
Parameter setting example using Modbus/TCP
Modbus/TCP is using 4 data words in each direction. The following table shows the parameter setting using
this protocol.
