Deadband
With the deadband the transmission rate of frequently changing values can be reduced. A new
value is only transmitted if the difference to the last transmitted value is equal or larger than
the deadband.
Control Relay Output
Block model
The Control Relay Output Block model determines how binary inputs (outputs from the
master's point of view) are switched.
Activation model
In this model the binary input is activated or deactivated on command for a certain time.
Complementary latch model
In this model the binary input is activated or deactivated on command and remains in this
state until the next command is received.
Complementary two-output model
In this model the binary input represents two binary inputs -
Close
and
Trip
. These are
represented as a two bit value. Bit 0 (0b00000001) represents the
Close
input, bit 1
(0b00000010) the
Trip
input. At any time none or at most one of these two inputs can be
active. So valid values are 0b00000000, 0b00000001 and 0b00000010. For reading back binary
inputs DNP3 only provides one bit. Thus for the Complementary two-output
model
Close
and
Trip
cannot be distinguished. Only the information whether any of the two
inputs is active is transmitted.
Limits
You can define up to 4096 values. The maximum number of all scalar (non-array) values plus the
size of all arrays is 8192.
Settings
Below the value list general settings can be configured:
Interval
Update interval of DNP3 Outstation driver interval in milliseconds.
Links
up to 4 links can be defined. A link is a connection between a Master and
an Outstation. For each link the local link address and the Master's link
address must be configured(valid values: 0-65519).
Port
TCP port number the DNP3 outstation is listening on
Event queue sizes
The event queue size determines how many events can be cached for the
corresponding data type until the Master next polls for an event. The
queue size must be between 1 and 1000.
Event Log Messages
The following section describes the messages that the DNP3 Outstation driver may log to
the Event Log. All messages are prefixed with the text
DNP3 outstation driver:
