Selection of Solution
► Local SI for Local Support► Wonderware SCADA selected for► Ease of configuration ► Minimal effort to integrate Date and Time
Stamp at source event streams through OPC server
System Implementation
► 960 Relay Contact Inputs COS monitoring► 960 Alarm Statuses Annunciated► Input discrimination to 200μseconds► Minimum Pulse Width 500μseconds► Time Stamping Accuracy 200μseconds
Disadvantages of Poll Response
Disadvantages of a poll/response network · Poll/Response uses %100 of available bandwidth.· The data "Transport" is the "Application". You can't break them apart.· One protocol for all field equipment limits deployment of new technology & impedes migration to new topologies.· It is not a "managed" network.· One-to-One data relationship between the Host and field equipment Master Slave
