(Z=F01 or Z=F05)
782 - 790 The data in messages 1:61 to 1:93, 107 and 108 are
(configurable as) read-write.
It takes approx. 530 ms to read these values and
from approx. 500 to a maximum of 1200 ms to write
them. After a write operation, the written value can
be called up after 200 ms (i.e. max. time for write +
check operations: 1200 + 200 + 510 = 1910 ms).
Values which have just been read are updated after
approx. 700 ms. Otherwise values are updated at
intervals of 5000 ms.

Setting values/
Protection parameters
(Z=F05)
The data in messages 1:101 to 1:106 are
(configurable as) read or read-write depending on
the release type.
It takes approx. 550 ms to read or write these values.
The values in 3WN6 are updated regularly.

Additional functions (1 and
2)
812, 820 The data in messages 1:111 and 1:112 are
(configurable as) read or read-write depending on
the release type.
It takes approx. 530 ms for the PLC to read these
values out of 3WN6 and from approx. 500 to a
maximum of 1200 ms to write them.
Values which have just been read are updated after
approx. 700 ms. Otherwise values are updated at
intervals of 5000 ms.
