Like the parameterisation of the PST DM word number (P10), the RST
DM word number is specified in one byte (0,1,2...255) in order not to
confuse the user with possibly varying parameter specifications; the word
number is converted into the CL500 format (byte address 0, 2, 4 ,6
....510) within the protocol;
9.11.1.6 PST Address: DM number — PW9
The PW9 parameter word indicates the data-module number for the PST;
data modules DM0 to DM255 can be addressed.

1 byte is available in the message for transfer of the DM offset; the offset
is therefore specified as a word number (0..255); the word numbers have
the following format for the various peripheral controllers:
- CL500 Word number 0, 1, 2, 3 ... 255
- PC600 Word number 0, 1, 2, 3 ... 255
- Siemens Word number 0, 1, 2, 3 ... 255
