A group telegram transmitted by the
media coupler on the TP side is checked
for transmission 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.
A broadcast telegram transmitted by the
media coupler on the TP side is checked
for transmission 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.
A physically addressed telegram
transmitted by the media coupler on the
TP side is checked for transmission
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.
i Deactivating the telegram repetition
if there are transmission errors
reduces the bus load, but also
reduces the transmission security!
At this point, it is possible to define when
the media coupler confirms the group
telegrams received on the higher-level
TP line.
