How to interpret the AHS36 / AHM36 Serial Number from CANopen object 650Bh and 1018.4h?

Serial Number interpretation and differences between type label and CANopen objects

The serial number at AHS36 / AHM36 get visible at type label or is available via CANopen objects 650Bh and 1018.4h.
But the serial number from type label (see picture below) and content of the object 650Bh (object 1018.4h is equal to 650Bh) are different displayed and additional the objects contains a type code as well.

Serial number on type label, for example 26020273, shows following information:
26 = Year 2026
02 = Calendar week 2
0273 = Counting number

Same encoder contains in the objects 650Bh / 1018.4h the serial number 0x231A0911 (588908817) which is different to 26020273.
Next example shows how the serial number from the CANopen objects must be decoded to get the similar value like on the type label.

650Bh / 1018.4h = 0x231A0911
0x23 = Type code AHS36A - (0x21 = AHS36B / 0x22 = AHM36B / 0x24 = AHM36A)
0x1A = 26 - Year 2026
0x0911 = CW (First 6Bit) & Counting number (Last 10Bit)
0x0911 = 0000 1001 0001 0001 → 0000 10 → 2 CW (calendar week)
0x0911 = 0000 1001 0001 0001 → 01 0001 0001  → 273 (counting number)

Summarize, object 650Bh / 1018.4h contains the same information like on type label, plus the product type but in a different coding.
