Channel "Local"
Channel type: Binary send Function: Parameter input mode 'local'.
The channel is not used for the DNP3 protocol.
Channel "LocalParameterInput"
Channel type: Data send
Function: Local parameter input
Local active parameters can be returned to the send block via "LocalParameterInput". The
data area corresponds to the data area set for "ParameterOutput" of the same object.
The address range is taken form the channel “ParameterOutput“.
If you do not require the parameter, leave it disabled.
Channel "ParameterOutput"
Channel type: Setpoint receive
Function: Parameter output
The parameters sent by the partner object or entered locally at "LocalParameterInput" are
output at "ParameterOutput".
The number of required elements, in other words the size of the data field is configured in
the “Number” (address) input box.
The configured number of values specifies how many DNP3 indexes are occupied
consecutively by the object starting with the specified start index. The following assignment
between the data type used and the index used applies:
Data type Range of values Number of DNP3 indexes
occupied
BYTE 0 .. 255 4 ... 48
CHAR Printable ASCII characters 4 ... 48
WORD 0 .. 65 535 2 ... 24
INT -32 768 .. 32 767 2 ... 24
DINT -2 147 483 648 .. 2 147 483 647 1 ... 12
DWORD 0 .. 4 294 967 295 1 ... 12
REAL ≈ -3,4 * 10 38 .. 3,4 * 10 38 1 ... 12
Note
Reducing network load
By reducing the maximum size (parameter “Number”), the message length can be reduced
to the actually required length if the entire data range of the object is not required. This saves
transmission time.
