3.1.6.2.4 Absolute Addressing
Direct presentation of individual memory cells (absolute addresses) based on
IEC 1131-3 is performed using character strings:
Tab. 3-13: Absolute addresses
such as word-by-word: %QW27 (28th word), bit-by-bit: %IX1.9 (10th bit in the 2nd word)
* The designator "X" for bits can be omitted
Note
The character strings for absolute addresses must be entered connected, i.e.
without spaces or special characters!
