CU320‑2 Control Units feature the following 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 x DRIVE‑CLiQ sockets for communication with other DRIVE‑CLiQ nodes, e.g. Motor Modules, Active Line Modules, Sensor Modules, Terminal Modules

• 12 parameterizable digital inputs (floating)

• 8 parameterizable bidirectional digital inputs/digital outputs (non-floating)

• 1 serial RS 232 interface (e.g. to connect the AOP30 Advanced Operator Panel)

• 1 interface for the BOP20 Basic Operator Panel

• 1 slot for the CompactFlash card on which firmware and parameters are stored

• 1 slot for mounting an option module (e.g. TB30 Terminal Board)

• CU320‑2 DP: 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 connector

• 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, for example, to include additional terminals or for communication purposes.

The status of the CU320‑2 Control Unit is indicated via multi-color LEDs.

As the firmware and parameter settings are stored on a plug-in CompactFlash card, the Control Unit can be changed without the need for software tools.

The CU320‑2 Control Unit can be mounted on the side of the Line Module via brackets integrated in a Line Module. The CU320-2 Control Unit can also be fixed to the wall of the control cabinet using the integrated fixing lugs.
