Description
Time delay in milliseconds between the
activation of the RTS signal and the start
of a new transmission.
Specifies the maximum number of times
that a message is retransmitted after a
timeout.
Specifies the maximum waiting time in
milliseconds within which the first byte of
a link layer response should have been
received.
Determines whether the link layer confirm-
ations are in use.
Specifies whether the collision detection
is used.
Maximum length of a data link fragment.
Delay in milliseconds between retransmis-
sions.
Delay in milliseconds between the test
function of link commands. If the value is
set to zero, the test function of a link com-
mand is not sent.
Specifies the time in seconds that the DNP
3.0 link waits for the end of the received
message.
The number of padding characters inser-
ted in the end of a telegram to delay the
passivation of the RTS signal.
Specifies if "Test Function for Link" is
enabled.
Specifies the transmission delay in milli-
seconds the protocol stack must wait after
receiving a CTS signal until starting the
transmission of a message.
