Prosoft MVI69E-AFC Enhanced Liquid & Gas Flow Computer for CompactLogix®

Modbus TCP/IP.

♦ User-configurable, allowing each of the meter runs to be individually set up to meet the specific requirements of an application.

Archiving

♦ Supports data archiving and event logging.

♦ Data archiving is available for each meter run, as two separately configurable files, one called “hourly” and the other called “daily”,

whose records are intended to implement the Quantity Transaction Records (QTRs) required by applicable measurement

standards. Under default configuration:

(a)  Records are written once each hour to the “hourly” file and once each day to the “daily” file, with additional records written to

both files upon occurrence of an event that could affect measurement results (such as the change in value of a significant

parameter).

(b)  Each record consists of 100 registers formatted with up to 50 data point values selected as being appropriate for the meter’s

configuration (type, product, etc.) and compliant with QTR requirements.

(c)  Each file is formatted for a few of the most recent records to be kept in higher-speed local storage plus 1440 more records in

larger-capacity, slower “extended” storage.

♦ Logging feature provides storage of up to 2.000 events and separately 2000 alarms.

Configurable Options

♦ User-selectable units for totalizers and flow rates on a per channel basis.

♦ Roll-over value for resettable and non-resettable totalizers for every meter channel.

♦ Process analog input units and ranges (pressure, temperature, differential pressure, density) from analog input modules and pulse

inputs from pulse/frequency input modules in a CompactLogix chassis.

♦ Fluid selection provides a choice of several liquid groups or gas measurement, using AGA, API, and/or ISO calculations.

♦ Event log reports for all security-sensitive configuration data (for example, orifice diameter) are date- and time-stamped. This data

can be saved to disk for importing into any spreadsheet or printed as a hard copy.

Modbus Interface

♦ SCADA communication is provided by the Modbus TCP/IP server and Modbus slave serial ports.

♦ Modbus table may be re-mapped as a virtual Modbus slave for user-assigned contiguous register polling by a SCADA client/master

(up to 20.000 registers).

♦ Poll remote devices (such as a Gas Chromatograph) by utilizing the Modbus Master serial port.

♦ Alarm, event, and meter archive log files may be downloaded in Enron Modbus format.

System Requirements - EAFC Manager

This configuration software is designed for Microsoft Windows 7. Minimum hardware requirements for a Windows 7 system are as listed

below. More advanced operating systems have significantly higher minimum requirements regardless of EAFC Manager minimum

requirements.

♦ 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor

♦ 1 GB RAM (32-bit) or 2 GB RAM (64-bit)

♦ 16 GB available hard drive space (32-bit) or 20GB (64-bit)

♦ Assigned IP Address
