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.

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.

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.
