Description

The CFE21A fieldbus card acts as the interface to the EtherNet/IPTM and Modbus TCP communication protocols.

The fieldbus interface makes it possible to connect the inverter to EtherNet/IPTM or Modbus TCP-based, higher-level automation, project planning, and visualization systems. The fieldbus interface has the following characteristics:

  • EtherNet/IPTM or Modbus TCP
  • Media redundancy
  • Integrated switch with cut-through procedure

When using the fieldbus interface, you can communicate directly with the devices via Ethernet and use the MOVISUITE® engineering software for startup, diagnostics, and parameterization purposes.

An integrated web server also makes it possible to access diagnostic values quickly and easily using a standard browser. You can reach the web server via the following address → http://IP address of the device.
