SIEMENS 6SL3055-0AA00-4CA4 BOP20 Basic Operator Panel | SINAMICS S120 Drive Platform
Engineering Background: The SIEMENS 6SL3055-0AA00-4CA4 is the BOP20 (Basic Operator Panel 20) designed exclusively for the SINAMICS S120 modular drive system — Siemens’ flagship multi-axis servo and vector drive platform for high-performance industrial automation. The BOP20 serves as the primary local HMI interface, enabling commissioning engineers and maintenance technicians to parameterize, monitor, and diagnose drive units directly at the cabinet without requiring a PC or STARTER software connection.
Product Positioning: Targeted at OEM machine builders, system integrators, and plant maintenance teams operating SINAMICS S120 Control Units (CU320-2, CU310-2, CU250S-2), the 6SL3055-0AA00-4CA4 is an essential commissioning and service tool for servo press lines, winding machines, multi-axis CNC platforms, and high-speed packaging systems. It is stocked and shipped globally by Konmask.com as a verified genuine Siemens component.

System Architecture & Signal Flow
The BOP20 (6SL3055-0AA00-4CA4) connects directly to the front interface slot of the SINAMICS S120 Control Unit. Communication occurs over the internal CU backplane bus — no additional PROFIBUS or PROFINET address assignment is required. The panel reads drive object parameters from the CU’s parameter memory and writes changes directly to non-volatile storage (EEPROM/flash). During normal PLC-controlled operation, the BOP20 operates in monitoring mode; local control commands are only active when the control source is switched to BOP20 via parameter p0700/p1000 settings.
Typical Wiring / Integration Path:
- SINAMICS S120 Control Unit (CU320-2 / CU310-2) → BOP20 front slot (direct plug)
- No additional power supply, cable, or fieldbus node required
- Compatible with single-axis and multi-axis drive object configurations

Technical FAQ
Q: Is the 6SL3055-0AA00-4CA4 compatible with SINAMICS S110 or S150?
A: No. The BOP20 is designed exclusively for SINAMICS S120 Control Units. S110 uses the BOP (6SL3255-0AA00-4CA1) and S150 uses the AOP30 panel.
Q: Can I use the BOP20 to upload/download parameter sets?
A: The BOP20 supports individual parameter read/write but does not support full dataset upload/download (RAM to ROM save is supported). For full dataset transfer, use STARTER or Startdrive with a PC.
Q: Does the BOP20 need to remain installed during machine operation?
A: No. It can be removed after commissioning. The Control Unit operates normally without the BOP20 installed. Many engineers leave it installed as a permanent service interface.
Q: What firmware versions are supported?
A: The 6SL3055-0AA00-4CA4 is compatible with SINAMICS S120 firmware V4.3 and above. Verify your CU firmware version via r0018 before installation.
Q: Can Konmask provide a test certificate or inspection report?
A: Yes. Contact [email protected] with your order number to request documentation for project or audit purposes.
