Notes:

Access indicates whether parameter can be Read and/or Written.

When a byte parameter is read, the upper 8-bits of the Modbus register will be 0. When a byte
parameter is written, the upper 8-bits must be set to 0.

Long integer parameters have a length of 4 bytes and are mapped on two consecutive Modbus
registers. The first register contains bit 32-16, the second register contains bit 15-0.

Floating point parameters have a length of 4 bytes and are mapped on two consecutive Modbus
registers. Floats are in single precision IEEE format (1 sign bit, 8 bits exponent and 23 bits fraction).
The first register contains bit 32-16, the second register contains bit 15-0.

String parameters can have a length of maximal 16 bytes and can take up to 8 Modbus registers
where each register contains two characters (bytes). The upper byte of the first register contains the
first character of the string. When writing strings, the write action should always start from the first
register as a complete block (it is not possible to write a part of a string). If the string is shorter than
the specified maximum length the string should be terminated with a 0.
