Siemens alarm 6035: Instead of %1 KB the system has only %2 KB of free user memory of type '%3'

What it means

After a cold start with default machine data, less free user memory (battery-backed 'S' or non-buffered 'D') was found than Siemens specifies for that 808D variant. It is a notice without functional impact, but it flags a memory configuration or hardware deviation worth checking after a service exchange.

Likely causes

• Cold start performed with standard machine data
• Reduced-capacity replacement PPU variant fitted
• Memory partitioning machine data changed
