R/W: Read and write

It is possible to both read and write to these registers.

W: Write only

These registers can only be written. Attempting read access to these registers causes an

error.

W/R0: Write only and read 0

These registers can only be written. Read access to these registers results in a zero as re-

sponse.

Datatype

This column contains the data type to be used for decoding the contents of each respective

ASCII

Each register (16 Bit) contains two ASCII characters. When the number is entered, the num-

ber of individual registers contained in the character string is determined.

Example:

Dez:1234567

Hex: 0X31, 0X32, 0X33, 0X34, 0X35, 0X36, 0X37

Zero-terminated: “12345670”

Hex: 0X31, 0X32, 0X33, 0X34, 0X35, 0X36, 0X37, 0X00

Number of registers = 4: Hex: 0X3231, 0X3433, 0X3534, 0X0037

Bit mask

Each bit (bit 15-bit 0) of the register (16 bit) is evaluated individually.

Example: “Resetting the tariff meter”

Bit 0: Reset tariff 1

Bit 1: Reset tariff 2

Bit 2: Reset tariff 3

Bit 3: Reset tariff 4

An individual tariff meter, or any combination of meters from all tariff meters can be reset.

Bool

This data type makes a logical statement.

0: false

1: true

Fl32

IEEE-754-single number 1.8.23 (32 bits, two 16-bit registers):

1 sign bit: positive and negative
