The OPC Portal Server is a windows-based application that allows OPC compatible
clients, such as HMIs and SCADA systems, to connect to one or more AADvance
controllers to access process data.
A PC implementation of SNCP supports 50 connections of which the OPC server
uses 2 per controller.
The current OPC implementation supports 6 controllers without significant
degradation of performance, however more than that number might degrade the
service.
The OPC Portal Server supports:
OPC Data Access, often known as 'DA', which provides real-time data from
AADvance controllers to OPC clients.
OPC Alarms and Events, often known as 'AE', which provides time stamped alarm
and event notifications.
A typical arrangement is shown in the illustration:
