Appendix D. EST3 ECP Connection Statistics:

The EST3 ECP protocol has two distinct levels:

•A poll-response connection is maintained by the EST panel acting as the master. The bytes transferred in this process are displayed on the FieldServer as SCADA bytes transmitted and received.

•The FieldServer acts as a client by inserting requests into its response messages; the EST panel then inserts the requested data into its subsequent polling messages. The bytes transferred in this process are displayed on the FieldServer as PLC bytes transmitted and received.

The following statistics are available on the Driver Aspects screen when viewing Connection Details (select the EST Connection in Connection Overview, and press space repeatedly to page to this screen):
