Memory/ Address Manager
The memory is divided into words, with a word being made up of 16 bits (bit0 to bit15).
The table below illustrates the memory data structure:
Note!
Boolean values are assigned byte-by-byte unless a single bit address is explicitly specified. A value
change of varbool1 AT% MW0 affects the range from % MX0.0 to % MX0.7
13.3.2 Flags
Tip!
The flag range size is dependent on the selected automation system.
Example1:
%MD48
% MD48
% MW96 % MW97
% MB192 % MB193 % MB194 % MB195
addresses bytes nos. 192, 193, 194 and 195 (48 * 4 = 192) in the flag range.
The first byte is byte no. 0.
Example2:
%MX5.0
addresses the first bit in the fifth word in the flag range.
(Bits are generally saved word by word.)
