For DNP3 SCADAPack Trend Analog and Trend Counter items, information is displayed in this format:
Master <DNP3 Local Address>: OS <Address>:<Point Type> Point Number <No.>: <Sample Value Type> Trend
Example:
Master 30000:OS 12:AI Point Number 5: Maximum Value Trend
(For a Trend item that defines how often the outstation samples an analog point’s data to ascertain the maximum value reached during each sampling period. The point for which data is being sampled resides at Point Number 5 in the outstation. The outstation’s address is 1, and it belongs to the outstation set that has a DNP3 Local Address of 30000.)
For DNP3 SCADAPack Trend Binary items, information is displayed in this format:
Master <DNP3 Local Address>: OS <Address>:<Point Type> Point Number <No.> Bits <No.>: <Sample Value Type> Trend
Example:
Master 30000:OS 12:BI Point Number 2 Bits 1:Current Value Trend
(For a Trend item that defines how often the outstation samples a binary point’s current value. The point for which data is being sampled resides at Point Number 2 in the outstation. The outstation’s address is 1, and it belongs to the outstation set that has a DNP3 Local Address of 30000.)
