Description

The CFP21A fieldbus card acts as the interface to the PROFIBUS communication protocol.

The fieldbus interface makes it possible to connect the inverter to PROFIBUS-based, higher-level automation, project planning and visualization systems. The fieldbus interface has the following characteristics:

• PROFIBUS DP/DP-V1 – cyclic and acyclic communication

For communication, the engineering PC with the USM21A interface adapter or the CBG21A keypad must be connected to the inverter.
