7SR220 Technical Manual
In this MODBUS implementation the 16 bit value is stored in a 16 bit register in Big-Endian format.
As an example, assume bits 1, 3, 9 and 12 are set. The binary representation of this would be
0000100100000101
it would look as follows:
On reception this register should be interpreted as a 16 bit integer.
