In address 5000 a 17Byte large control word is deposited.
A part of this control word is used for deletion of energy:
Byte 7 > 0, delete real energy
and
Byte 8 > 0, delete reactive energy.
In order to overwrite a Byte, first
read control word,
overwrite Byte7/8 with e.g. 1
and rewrite the changed control word to address 5000.
Attention!
Changing the control Byte incorrectly can lead to
malfunctions of the UMG 503.
