The CU310?2 Control Unit drives Power Modules in blocksize format via the PM?IF interface. DRIVE?CLiQ motors or Sensor Modules (SMC) can also be connected to the integrated DRIVE?CLiQ socket to permit the operation of motors without a DRIVE?CLiQ interface.

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. The CU310?2 Control Unit requires a CompactFlash card with firmware V4.4 or higher.

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 cycle 500 ?s
• Connects to controls as PROFINET IO devices using PROFIdrive compliant with Specification V4
• Standard TCP/IP communication for engineering processes with the STARTER commissioning tool and for accessing the integrated web server
• 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 supply voltage must be connected to terminal X124 for the digital outputs to be used. To operate the CU310?2 Control Unit, a CompactFlash card with firmware V4.4 or higher is required.
