Product Overview
The Siemens 6AG1591-1BA02-2AA0 is a SIPLUS S7-1500 Front Flap CPU 70 mm used as a replacement front assembly for compatible 70 mm S7-1500 CPUs. It belongs to the SIPLUS S7-1500 accessory range and is intended for maintenance, replacement, and service work on installed automation systems.
The front flap is mounted on the front side of the CPU and forms part of the physical operator interface. It protects the front area of the controller while allowing access to the CPU’s local operating and diagnostic elements.
For maintenance teams, this type of component is useful when the existing front flap is damaged or needs replacement while the CPU and its control program remain in service. Replacing the front assembly avoids unnecessary replacement of the complete controller.

Product Features
- SIPLUS S7-1500 front flap for 70 mm CPU assemblies.
- Intended for replacement and maintenance of compatible S7-1500 CPUs.
- Front-mounted mechanical assembly for the CPU.
- Conformal-coated SIPLUS construction.
- Suitable for SIPLUS applications with extended environmental requirements.

- Suitable for planned maintenance and corrective service.
- Supports continued use of the installed S7-1500 controller.
Working Principle
The 6AG1591-1BA02-2AA0 is a mechanical front component rather than an active PLC module. It does not execute the user program, process field signals, or handle network communication.
During normal operation, the front flap is mounted directly on the compatible S7-1500 CPU. It forms part of the CPU’s front-facing assembly and protects the associated interface and display area.
During service, the existing front flap can be removed and the replacement assembly installed on the CPU. The controller’s program, I/O modules, network configuration, and connected field devices remain part of the existing automation system.
The SIPLUS construction is intended for applications requiring the environmental characteristics associated with SIPLUS equipment.
Role in a SIPLUS S7-1500 Control Architecture
The front flap is positioned at the physical interface of the CPU and does not participate directly in the PLC control loop.

Installation and Maintenance
- Confirm CPU compatibility — Verify that the installed controller uses the compatible 70 mm CPU front assembly.
- Check the part number — Compare 6AG1591-1BA02-2AA0 with the installed component and maintenance documentation.
- Shut down the equipment — Stop the machine or process according to the approved operating procedure.
- Isolate the power supply — Follow the applicable electrical isolation and lockout procedure before working on the controller.
- Protect the CPU — Prevent dust, moisture, metal particles, and other contaminants from reaching the exposed front area.
- Remove the existing front flap — Release the existing component carefully to avoid damaging the CPU housing.
- Inspect the mounting area — Check the CPU front section for broken retaining elements, contamination, or mechanical damage.
- Align the replacement part — Position the 6AG1591-1BA02-2AA0 correctly against the CPU front section.
- Secure the assembly — Make sure the replacement front flap is fully seated and mechanically retained.
- Check front operation — Confirm that the flap and accessible CPU operating elements move correctly.
- Restore the controller — Re-energize the system according to the plant commissioning procedure.
- Verify diagnostics — Check the CPU status and diagnostic indications after maintenance and record the replacement in the service documentation.
