6 Operation
6.1 Requirements for Successful Operation
The EtherNet/IP Card is conformance-tested to ODVA. For successful operation, the scanner must also support all functions and
interfaces described in this manual.
N O T I C E
The available features and parameter details may vary according to the model and software version of the soft starter. Refer to
the VLT® Soft Starter MCD 600 Operating Guide for details of parameters and supported features.
6.2 Device Classification
The EtherNet/IP Card is an I/O adapter and must be managed by an I/O scanner over Ethernet.
The EtherNet/IP Card supports both implicit (cyclic) and explicit (acyclic) messaging.
6.3 Ensuring Safe and Successful Control
Data written to the device remains in its registers until the data is overwritten or the device is reinitialized. If the soft starter is con-
trolled via parameter 7-1 Command Override or is disabled via the reset input (terminals RESET, COM+), fieldbus commands should
be cleared from the registers. If a command is not cleared, it is re-sent to the soft starter once fieldbus control resumes.
