7.1 Data types and type of access
The Chapter 7.2 contain descriptions of all process values (variables) including
their addresses, data type and type of access.
Meaning:
7.2 Modbus addresses of important device and process data
R Read only access
W Write access
R/W Read and write access
char xx Character string consisting of ASCII characters (8 bits) with the
length xx;
xx = Length including the "\0" character string end character
2 characters are read and written in a word.
word Unsigned Integer 16 bit (1 word)
int Signed Integer 16 bit (1 word)
long Signed Integer 32 bit (2 words)
float Float value (4 byte = 2 words) as per IEEE 754
bool Bool can be read and written as word,
its value range is 0 … 1
byte Byte (8 bit) can be read and written as word,
its value range is 0 … 255
Bit x Bit No. x (bit 0 is always the bit with the lowest value)
