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.
