ioLogik E2260 User’s Manual Active OPC Server Lite
5-4
The “push” technology also includes the update for the tags. When the I/O the status changes,
there will be updates from the ioLogik to Active OPC Server Lite. Compared to constantly polling
(pull-based) the status, this feature efficiently reduces the network bandwidth usage and speeds up
the response time with event-driven, push-based status updates. At the same time, the heartbeat
function visual confirms that ioLogik is “alive” and working.
Features of Active OPC Server Lite
Automatic tag generation
Without specifying IP addresses, I/O channels, and data formats one by one or editing and
importing any configuration text files, Active OPC Server Lite creates the tags for the target
ioLogik automatically. These tags are not fixed but created by users. After selecting the channels
required to be update to Active OPC Server Lite, it will generate the tag configuration without
asking any questions. Training for installation and configuration should be required to implement a
general OPC Server package. For ioLogik users, learning the OPC technology, looking up Modbus
address, configuring data format, assigning target IP and so on are not required.
Active tag update with heartbeat detection
ioLogik uses “Active” technology to update the I/O status. This includes the tag status update to
Active OPC Server Lite. Compared to traditional OPC Servers, this mechanism reduces Ethernet
bandwidth usage by 80%. At the same time, it increases the response time of the I/O channels 7
timers faster than before. The SCADA PC can now also be load balanced for its CPU time because
it simply waits for updates instead of polling the I/O channel all the time.
