Note that a Data-set event can consume any number of event buffers,
depending on the Data-set configuration. This is only applicable for Data-set
events. The event for other objects consumes a single event buffer. When using
Data-set events, increase the number of events in the DNP3 Slave
configuration.
Descriptor Element Configuration: Each Descriptors element is configured by
clicking on the individual DSX under the DNP3 Data-set Descriptor. Add new
index by clicking Add in each DSX.
Descriptor Code: NAME, DAEL, PTYP
Data Type Code: VSTR, UINT, INT, FLT, OSTR, BSTR, TIME
Max Data Length (bytes): 0…255
Ancillary Value: Any string. This can be a binary array or ASCII string, up to
32 bytes.
Point Addressing under Descriptor Element Configuration: Data-Set value for
each Data-Set element is configured by:
• Point Address Type
•Point Index
Point Address Type Point Type Point Index Event Occurrence Condition
Empty NONE: No point type is associated. 0 No Event is generated.
Standard DNP3 Point
BI: Binary input 0…4095
When the Point Type and Point
Index are pointing a specific point,
if the value of the point is
changed, an event is generated.
B2I: Double-bit input 0…2047
CI: Counter 0…511
AI: Analog input 0…767
BCD: BCD point 0…255
Variable Select the tag from the controller. 0
Event is generated based on the
condition of the variable tag
selected.
