The measured frequency value is transmitted via the communication interface if
it differs by the set delta quantity from the last measured value transmitted.
Note: This setting is hidden unless an IEC 870-5 protocol is enabled.

The telegram is transmitted if a measured value differs by the set delta quantity
from the last measured value transmitted.
Note: This setting is hidden unless an IEC 870-5 protocol is enabled.

All measured values are transmitted again via the communication interface after
this time period has elapsed – provided that transmission has not been triggered
by the other delta conditions.
Note: This setting is hidden unless an IEC 870-5 protocol is enabled.

[spacer]
A continuous or background general scan means that the P634 transmits all
settings, signals, and monitoring signals through the communication interface
during slow periods when there is not much activity. This ensures that there will
be data consistency with a connected control system. The time to be set defines
the minimum time difference between two telegrams.
Note: This setting is hidden unless an IEC 870-5 protocol is enabled.

Setting for the length of the higher-order communication address.
Note: This setting is hidden unless the IEC 870-5-101 protocol is set.
