How to identify your Siemens SIMOS12.1 file

How the numbers on this ECU type start:

• HW CASC1… 15 of the 26 files with a HW number, 58%
• HW 8V090… 5 of the 26 files with a HW number, 19%
• SW 1027… 7 of the 16 files with a SW number, 44%
• SW 1026… 5 of the 16 files with a SW number, 31%

A HW number alone does not pick the file: CASC1CC5.DAT carries 4 SW versions here. Compare both numbers with your read.
