OPC90 Server
7.28 Sequence of Events (SOE)
The SOE OPC90 block is used to monitor and retrieve sequence of events data
from Bailey Sequence of Events Log blocks (function codes 99 and 243).
OPC90 supports up to four ABB Bailey sequence of events recorders by allowing
definition of four SOE point sets. Each point set consists of 512 points. The
Edit->SOE Point Names menu selection is used to define the SOE point sets.
Configuration of this block includes selection of the SOE point name set it is to be
associated with.
Restrictions: This OPC90 block can be utilized with all Bailey interface types
except serial port module (SPM & CPM02).
