R: Register
The “R” stands for Register and designates the lines that each describe a register.
Only lines that also contain registers are relevant for automatic processing of the register ta-
ble.
U: Unused
The “U” describes unused entries. These can be, e.g., address ranges that do not have a
function (yet) and are reserved.
E: End
The “E” describes the end of the table.
Dec: Decimal address
The second column of the register table contains register addresses in decimal form.
Hex: Hexadecimal address
The third column of the register table contains register addresses in hexadecimal form.
Count
The “Count” column displays the number of registers required for the function described in
this line. The required number is directly dependent on the data type.
Short designation
The “Short designation” column contains the abbreviated designations of the registers. The
short designations are unique, so that all other data can be referenced using the short des-
ignations.
Unit
The unit for the process values is given in the “Unit” column. For example, the unit for the
voltages is volt [V].
Divider
The “Divider” column states the divider by which the value is to be divided to get the correct
value. This is necessary, e.g., if the data type is an integer value, but a decimal fraction has
to be entered.
Example:
If the harmonics are specified as percentage with signed integer, but have to be output with
a precision of a tenth of a percent. In this case, for example, 15.2% is used as 152 with di-
vider 10.
R/W: Read/write access
This column specifies which access is permitted for the respective register.
R: Read only
These registers can only be read. Attempting write access to these registers causes an er-
ror.
