DFC compatibility
You can use this parameter to set how the device is to use the DFC bit (Data
Flow Control) in the control field. You can select the following options:
Option Description
Standard The device sets the DFC bit in each response to a com-
mand. The device thus indicates that the master may not
send any further commands. The master must react to
the ACD bit (Access Demand) and retrieve the response
to the command e.g. via a request for data of class 1
from the slave queue.
Alternative The device sets the DFC bit in a response if a second
command is received without the master having previ-
ously sent a request for data of class 1.

Reference time
You can use this parameter to set which time is to be transmitted by the con-
trol system. The device uses this information for time synchronization
[
► Section 8.7.3, Page 97]. You can select the following options:
Option Description
Local The control system transmits the local time.
Note: If you use this option, you must deactivate the au-
tomatic changeover between daylight saving time and
standard time. Otherwise the device will use an incorrect
time.
UTC The control system transmits the time as UTC. The de-
vice calculates the local time from UTC and the set time
zone [
► Section 8.7.3.3, Page 99].
