Power Modules in chassis format are controlled from the CU310-2 Control Unit via the DRIVE-CLiQ interface. Sensor Modules and Terminal Modules must be connected to the free DRIVE‑CLiQ sockets of the Power Module.

With the BOP20 Basic Operator Panel, parameters can be changed directly on the device. The BOP20 Basic Operator Panel can also be snapped onto the CU310‑2 Control Unit during operation to perform diagnostics.

The CU310‑2 Control Unit and other connected components are commissioned and diagnosed with the STARTER commissioning tool.

A CU310-2 DP Control Unit communicates with the higher-level control system using PROFIBUS and the PROFIdrive V4 profile.

A CU310‑2 PN Control Unit communicates with the higher-level control system using PROFINET IO and the PROFIdrive V4 profile.

The SINAMICS S120 drive system with the CU310‑2 PN Control Unit then assumes the function of a PROFINET IO device and can perform the following functions:

• PROFINET IO device
• 100 Mbit/s full duplex
• Supports real-time classes of PROFINET IO:
  • RT (Real-Time)
  • IRT (Isochronous Real-Time), minimum send clock 250 Ојs
• Connects to controls as PROFINET IO devices using PROFIdrive compliant with Specification V4
• Standard TCP/IP communication for engineering processes using the STARTER commissioning tool
• Integrated 2-port switch with two RJ45 sockets based on the ERTEC ASIC. The optimum topology (line, star, tree) can therefore be configured without additional external switches.

A 24 V power supply must be connected to terminal X124 in order to use the digital outputs. To operate the CU310‑2 Control Unit, a CompactFlash card with firmware V4.4 or higher is required.
