Write access to a holding register of the mirror range (D380 - D39F) also changes the corresponding holding
register of the original range (D000 - D614).
Write access to a holding register of the original range (D000 - D614) also changes the corresponding holding
register of the mirror range (D380 - D39F).
Example:
Holding register address Content
D480 D001 (set value)
D481 D106 (operating mode Parameter set 1)
D482 D000 (reset)
D483 D009 (operating hours counter)
With read access to the holding register D380, the set value is obtained.
With write access to the holding register D380, the set value is set.
At the same time the content of the holding register D001 (set value) is set to the same value
With read access to the holding register D381, the operating mode (parameter set 1) is obtained
With write access to the holding register D381, the operating mode (parameter set 1) is set
At the same time the content of the holding register D106 (operating mode (parameter set 1)) is set to the
same value
The same applies accordingly to the following holding registers.
With joint read access to the holding registers D380 - D383, the content of the holding registers Set value,
Operating mode (parameter set 1), Reset and Operating hours counter is obtained with a single command.
Joint write access to the holding registers D380 - D383 makes it possible to write the content of the holding
registers Set value, Operating mode (parameter set 1), Reset and Operating hours counter with a single
command.
2.50.1 Mirrored holding registers
Address : D380 - D39F
Write authorization : see Original registers
Coding : see Original registers
The content of the holding registers defined in D480 - D49F is mirrored here
