Special assembly instances
In addition to the normal connection (Exclusive Owner) where certain input and output instances are
used, the PLC can also open INPUT ONLY and LISTEN ONLY connections to the drive. When using
the INPUT ONLY connection, the PLC opens a connection where it only receives data from the drive.
It does not send any commands to the drive. When opening the INPUT only connection, the PLC user
must set the output instance to 253 and the size to 0. The input instance can be selected freely. The
INPUT ONLY connection can be the only connection to the drive, where as the LISTEN ONLY
connection always requires a normal "Exclusive Owner" connection. When opening the LISTEN
ONLY connection, the PLC user must set the output instance to 254 and the size to 0. The input
instance in LISTEN ONLY connection and the Data cycle (packet rate) must match to the one used in
the Exclusive Owner connection.

EtherNet/IP connection example
Preparing the connection
1. Set the EtherNet/IP as the active protocol from the panel parameters.
2. Set proper IP settings.
3. Open a connection with the settings described in the following table.
4. Before trying to run motor, see Chapter 14 "APPENDIX 4 - FIELDBUS PARAMETRISATION" for
information on how to configure the drive.
1. Set control word to 0x0 (00000000).
2. Set control word to 0x61 (01100001) (NetRef, NetCtrl and Run Fwd enabled).
3. Drive status is: “RUN”.
4. Set speed reference to 0x05EE (=25%).
5. Actual speed is 0x05EE (= 25% if MinFreq is 0Hz and MaxFreq is 50Hz).
6. Set control word 0x60 (01100000).
7. Drive status is: “STOP”.
