The CU320?2 Control Unit features the following connections and interfaces as standard:

• Fieldbus interface:
  • CU320?2 PN: 1 PROFINET interface with 2 ports (RJ45 sockets) with PROFIdrive V4 profile
  • CU320?2 DP: 1 PROFIBUS interface with PROFIdrive V4 profile
• 4 DRIVE-CLiQ sockets for communication with other DRIVE-CLiQ devices, e.g. Power Modules, Terminal Modules
• 12 parameterizable digital inputs (floating)
• 8 parameterizable bidirectional digital inputs/outputs (non-floating)
• 1 serial RS232 interface
• 1 interface for the BOP20 Basic Operator Panel
• 1 slot for the CompactFlash card on which firmware and parameters are stored
• 1 slot to install an option module for the interface expansion
• 2 rotary coding switches for manually setting the PROFIBUS address
• 1 Ethernet interface for commissioning and diagnostics
• 3 measuring sockets and one reference ground for commissioning support
• 1 connection for the electronics power supply via the 24 V DC supply connector
• 1 PE connection
• 1 ground connection

A shield connection for the signal cable shield of the option module is located on the CU320?2 Control Unit.

The available option slot is used to expand the interfaces, e.g. number of terminals.

The status of the CU320?2 Control Unit is indicated via multi-color LEDs.
As the firmware and set parameters are stored on a plug-in CompactFlash card, the Control Unit can be changed without the need for tools.
