ioLogik E2200 Series Active OPC Server
6-5
Faster, More Accurate Data Collection than Traditional “Pull
Technology”
Moxa has pioneered the concept of “active type” OPC software in the automation industry. The patented Active
OPC Server offers nonpolling architecture alongside the standard OPC protocol, giving users the alternative of
active, push-based communication from Moxa’s remote I/O devices. This adaptation of push technology means
that I/O status will be updated at the Active OPC Server only when there is an I/O status change, a
pre-configured interval is reached, or when a request is issued by a user. This application of push technology
cuts metadata overhead, resulting in faster I/O response times and more accurate data collection than
traditional pull-based architectures. With Moxa’s “active technology” advantage, users can now instantly
receive alarms and real time updates allowing for timely risk response.
