Description
The Siemens 6ES5631-0AA11, also known as the PG 631, is a specialized CRT programming terminal designed for the legacy Simatic S5 industrial automation system. This unit serves as a critical engineering and troubleshooting interface, allowing technicians to perform direct diagnostics, modify program logic, and manage register parameters within S5 programmable logic controllers. It is a robust, field-hardened tool essential for maintaining legacy installations in sectors such as power generation, petrochemical processing, and heavy industrial manufacturing.
Features
- Integrated monochromatic CRT display optimized for ladder logic and statement list visualization.
- Dedicated serial interface for direct connection to Simatic S5 processor programming ports.
- Ruggedized desktop housing with integrated thermal management for factory floor environments.
- Full-travel mechanical keyboard for precise input of STEP 5 software commands and data block modifications.
- German-localized firmware and keyboard layout.
Applications
The PG 631 is primarily used for the maintenance and commissioning of Simatic S5 PLC systems. It enables field engineers to perform real-time code debugging, memory module access, and variable monitoring to reduce downtime in legacy automation environments.

Installation Guidelines
- Ensure the unit is placed on a stable, flat surface with adequate clearance around the cooling vents to prevent overheating of the CRT and internal power components.
- Verify that the power supply voltage matches the unit's requirements before connecting to the AC mains.
- Use only original Siemens programming cables for connection to the S5 processor to ensure proper signal integrity and communication.
- Handle the CRT display with care; avoid physical shocks or vibrations that could damage the vacuum tube or internal high-voltage circuitry.
- Always power down the programming unit before connecting or disconnecting the interface cable from the PLC chassis to prevent potential electrical damage to the communication ports.
FAQ
Is the 6ES5631-0AA11 compatible with modern Windows-based software?
No, this unit is a dedicated hardware terminal designed to run native STEP 5 utility configurations for the Simatic S5 system. It is not intended for use with modern PC-based programming software.
Does this unit feature a standard QWERTY keyboard layout?
