Product Overview

The Siemens 6AG1591-1BA01-2AA0 is a SIPLUS S7-1500 front flap V2 CPU 70 mm used as a spare display/front assembly for selected S7-1500 CPUs. It is based on the standard 6ES7591-1BA01-0AA0 design and adds conformal coating for SIPLUS applications.

This V2 front flap is intended for 70 mm wide S7-1500 CPUs, including CPU 1515(F)-2 PN, CPU 1516(F)-3 PN/DP, CPU 1517(F)-3 PN/DP, and CPU 1518(F)-4 PN/DP. It can be used when the original CPU display/front assembly needs replacement without changing the CPU itself.

The unit is particularly useful for maintenance work on SIPLUS control cabinets where the CPU remains installed and only the front display assembly needs to be replaced.

Working Principle

The 6AG1591-1BA01-2AA0 does not perform PLC logic processing, I/O acquisition, or communication by itself. Its function is associated with the front display and front flap assembly of the compatible S7-1500 CPU.

During normal operation, the front assembly is mounted directly on the CPU and forms the operator-facing section of the controller. The display allows the user to access CPU status information and diagnostic information locally.

When the original front/display assembly is damaged or needs replacement, the 6AG1591-1BA01-2AA0 can be installed as the corresponding SIPLUS spare part. The CPU, user program, I/O modules, and communication configuration remain part of the existing automation system.

The conformal-coated SIPLUS construction is intended for applications where the controller operates under the environmental conditions specified for the SIPLUS version.


Role in a SIPLUS S7-1500 Control Architecture

The front flap is positioned at the operator-facing side of the CPU rather than in the signal or communication path.

Industrial Applications

Application Typical Use
Factory Automation Replacement of a damaged or worn CPU front/display assembly in S7-1500 control cabinets
Process Machinery Maintenance of SIPLUS controllers installed on machines operating under extended environmental conditions
Production Lines Keeping installed CPU assemblies serviceable without replacing the complete controller
Packaging Equipment Spare-part replacement during planned maintenance
Material Handling Maintenance of S7-1500 CPU front assemblies in conveyor and handling systems
Infrastructure Control Service work on SIPLUS-based automation cabinets
Retrofit Projects Replacement of an existing front/display assembly while retaining the installed CPU

Installation and Maintenance

  1. Verify the CPU model — Confirm that the installed CPU is one of the compatible 70 mm S7-1500 CPU types before ordering or installing the spare part.
  2. Check the part number — Compare the replacement part number with the existing component and maintenance documentation.
  3. Isolate the controller — Follow the plant’s electrical isolation procedure before removing the front assembly.
  4. Protect the CPU — Prevent dust, moisture, metal particles, and other contaminants from entering exposed areas during replacement.
  5. Remove the existing front assembly carefully — Avoid excessive force on the mechanical retaining points and connected components.
  6. Inspect the mounting area — Check the CPU front section for broken clips, contamination, or other mechanical damage.
  7. Install the replacement assembly — Position the 6AG1591-1BA01-2AA0 correctly and secure it according to the S7-1500 installation procedure.
  8. Check mechanical alignment — Make sure the front flap sits correctly against the CPU housing and can move or close normally.
  9. Restore power according to procedure — Re-energize the controller only after the replacement has been inspected.
  10. Check the CPU display — Confirm that the display operates correctly and that status information can be viewed.
  11. Review diagnostic information — Check the CPU status and diagnostic indications after maintenance.
  12. Record the replacement — Update the maintenance record with the installed part number and service date for future troubleshooting.
