The generic ID can be derived from the manufacturers ID list maintained by DLMS User Association. This list can be found here: https://www.dlms.com/flag-id/flag-id-list
Calculation of the 16-bit manufacturer ID used in EN 13757-4 based on those three letter codes is like this: 32 x 32 x <A> + 32 x <B> + <C>
Whereas, <A>, <B> and <C> correspond to the number of the character within the alphabet.
Calculation example
The three letter code for manufacturer STACKFORCE is STF.
The character number within the alphabet for the single letters are: S=19, T=20 and F=6.
This leads to: 32 x 32 x 19 + 32 x 20 + 6 = 20102 = 0x4E86
