Page 3 of 25 EST3 DESCRIPTION The EST3 External Communications Protocol (ECP) driver allows the FieldServer to transfer data to and from EST devices over RS-232 or RS-485 (with converter) serial ports using the EST3 ECP protocol. In the EST application the FieldServer always emulates a Client.

Gateway Type III is recommended. The EST3 panel monitors the quality of communications to the FieldServer and will detect a poor connection. Poor connections are normally caused by inappropriate selection of gateway type, but can also be related to installation quality.
This section documents and describes the parameters necessary for configuring the FieldServer to communicate with an EST3 Server. The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable the FieldServer for EST3 communications, the driver independent FieldServer buffers need to be declared in the “Data Arrays”...

The write priority has the possible values of Set, Latch, Low, Medium, and High. These are encoded as 00h, 01h, 02h, 03h and 04h respectively. Report and Delta Service: The EST ECP3 Report and Delta services report point status slightly differently. The FieldServer EST3 driver deals with these differences as follows: Appendix A.1.1. Report Service (regular polling): The full 16-bit point status is stored to the Read Map Descriptor’s Data Array.
The EST3 panel is only able to send/accept Acknowledgement when the panel is in Proprietary Mode. Contact EST (Edwards Systems Technology) for information on configuring the panel.

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.
