ioLogik E1500 Series Active OPC Server Utility
5-4
The pushtechnology also includes the update for the tags. When the I/O status changes, the ioLogik will send
updates to the Active OPC Server. Compared to polling the status (the so-called pull-based method), this
feature efficiently reduces network bandwidth usage and speeds up response time with event-driven,
push-based status updates. At the same time, the heartbeat function monitors the system’s basic signs of life.
