Description
Specifies if only one application
layer command (e.g. poll) may
be active at any time. Enabling
this configuration is useful
when the communication hard-
ware does not support collision
detection. The poll intervals
defined with the topic configur-
ation tool define the intervals
the IED is tried to be polled.
When multiple IEDs are connec-
ted, the actual polling interval
may be longer. When multiple
simultaneous application layer
commands are allowed, the
command's transmission is not
related to the state of the other
IEDs connected to the same
communication channel. This
mode of operation can be used
in systems with collision detec-
tion.
Data polling period.
Specifies the time (in seconds)
that the DNP 3.0 link waits for
the end of the received mes-
sage.
The number of padding charac-
ters inserted in the end of a
telegram to delay the passiva-
tion of the RTS signal.
Specifies if 'Test Function For
Link' is enable.
False = Enabled
True = Disabled
Delay in milliseconds between
test function link commands. If
the value is zero (0), the test
function of link command is not
sent.
Specifies the transmission
delay in milliseconds the pro-
tocol stack must wait after
receiving a CTS signal until
starting the transmission of a
message.
