Broadcast telegrams
transmit unfiltered
block
This parameter determines whether broadcast telegrams are forwarded from the
lower-level RF side to the higher-level TP side (routing RF -> TP).
transmit unfiltered
All broadcast telegrams are transmitted.
block
All broadcast telegrams are blocked. No broadcast telegram can pass the coupler
from RF to TP.
physically addressed telegrams
transmit unfiltered
block
filter (depending on target & coupler ad-
dress)
This parameter determines whether physically addressed telegrams are forwarded
from the lower-level RF side to the higher-level TP side (routing RF -> TP).
transmit unfiltered
All physically addressed telegrams are transmitted.
block
All physically addressed telegrams are blocked. No physically addressed telegram
can pass the coupler from RF to TP. This means no TP or IP devices can be pro-
grammed via the RF side (device domain)!
filter (depending on target & coupler address)
Only physically addressed telegrams with a target address which does not match the
coupler area or line address are forwarded. Physically addressed telegrams with a
target address matching the coupler area or line address are blocked.
Repetitions in case of TP transmission errors
Group telegrams
no
yes
A group telegram transmitted by the device on the TP side is checked for transmis-
sion errors. This parameter determines whether the forwarded telegram is to be re-
peated up to three times when a BUSY or a NACK confirmation signal is received, or
when there is no ACK confirmation signal on the higher-level TP line.
Broadcast telegrams
no
yes
A broadcast telegram transmitted by the device on the TP side is checked for trans-
mission errors. This parameter determines whether the forwarded telegram is to be
repeated up to three times when a BUSY or a NACK confirmation signal is received,
or when there is no ACK confirmation signal on the higher-level TP line.
