Overview
Introduction
The Allen-Bradley DataSite controller is an excellent remote terminal unit for
service in harsh and extreme industrial environments such as oil, gas, pipeline,
and electrical utility applications. It is ideal for applications that require wide
temperature ratings and low power consumption, and applications that are
remote and powered by solar cells or wind power.
The DataSite controller has a high-performance 32-bit ARM processor with
several communications options. An Ethernet port, two serial ports
(RS232/RS485) and one HART multi drop interface are built in. Native
protocols include Modbus RTU, Modbus ASCII, Modbus TCP/IP and
DNP 3.0.
The DataSite controller can store a total of:
• 700 event records
• 300 alarm records
• Hourly records of up to 35 days for each meter run
A maximum of 30 items for each day can be stored.
• Daily records of up to 35 days for each meter run
The DataSite controller can be programmed by using DataSite Workbench.
Workbench is a software environment designed to facilitate the task of
automation throughout the life cycle of a system, from system design to
commissioning, operation, and maintenance. To view valves, pumps and
meters over the Internet, use DataSite Screen Builder. Screen Builder is an
embedded web technology which allows the DataSite controller to act as a web
and event-based data server.
