8 Overview
1758-FLO DataSite controllers
In addition to the features listed in preceding sections, the 1758-FLO DataSite
controllers provide the additional feature of being able to calculate gas flow.
1758-FLO DataSite controllers contain the 1758-FLO flow measurement
algorithm which conforms to the following standards:
AGA-3 (1992 version)
(1)
orifice metering of natural gas and other
related hydrocarbon fluids;
AGA-7
(1)
measurement of gas by turbine meters;
AGA-8
(1)
compressibility factors of natural gas and other related
hydrocarbon gases.
The 1758-FLO controller can be configured by using the DS FloConfig
software. This tool provides functions such as reading and revising parameters,
reading historical data and monitoring measurement results.
Features at a Glance
Advanced 32-bit processor with embedded real-time multi-task
operating system (RTOS).
8 analog inputs (2 with point-to-point HART interface), 2 analog out, 8
discrete inputs, 4 discrete outputs, and 3 pulse inputs.
Embedded Ethernet, two serial ports (RS232/RS485) and one HART
multi-drop interface; native protocols include Modbus RTU, Modbus
ASCII, and Modbus TCP.
6M Flash, 1M RAM, and 32K ferroelectric RAM for long-term storage
of configured parameters.
HiBeam technology that allows the DataSite controller to act as a web
and event-based data server. HiBeam also has tools for interfacing with
your controller-based data through a standard web browser.
Conformity to IEC61131-3. Supports LD, FBD, IL, ST and SFC
programming languages.
Isolation of power supply, signal output and input terminals from the
main control circuit.
Standard industrial design and DIN rail mounting option, which are
convenient for field installation and configuring interior hardware.
(1)
The 1758-RTU controller does not have AGA-3, AGA-7 or AGA-8 calculations.
