1. 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.
The FieldServer makes use of the following ECP Services:
Read Operations:
• Report Service
• Delta Service
Write Operations:
• Command Service
All read points are continually updated using the Report Service; response times are enhanced using
Delta Service broadcasts by the EST3 panel.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.
