Addresses are the protocol addresses of the address list; values are big-endian. The device also serves them little-endian at the address + 32768.
Readings of type short are multiplied by 10, 100 or 1000 in the device (see scale); they do not include the transformer ratios, unlike the float readings.
The text registers 25000 and 25128 are given a length of 128 registers (the gap between them); the address list does not state the length.
