The Siemens 6FC5370-5AA20-0AA0 is SINUMERIK 828D CNC hardware identified by Siemens as the PPU 261.2 horizontal Panel Processing Unit. It combines the operator-facing panel and CNC processing hardware used in machine-tool control architectures based on the SINUMERIK 828D platform.
This order number is intended for horizontal installation and must be matched to the machine configuration, SINUMERIK software level, drive system, operator-panel connections, and field wiring before replacement. Siemens lists the unit as a spare part and gives a net weight of 4.5 kg with packaging dimensions of 525 x 390 x 140 mm.
Siemens records 6FC5370-5AA20-0AA0 as cancelled from 5 October 2015 and identifies 6FC5370-5AA30-0AA0 as the successor type. A retrofit should therefore include a comparison of hardware generation, system software, licenses, machine data, interfaces, and the original installation orientation rather than relying on the article number alone.
