Battery Life Advisory

The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to
back up the real-time clock and CMOS. The battery should last for the life of the module. The module must be
powered for approximately twenty hours before the battery becomes fully charged. After it is fully charged, the battery
provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is
fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user replaceable.

Note: Due to the broad range of meters in the market today, refer to the manufacturer specification
to evaluate the use of the module (even if listed here).

Note: For Vortex, Ultrasonic, or Coriolis meters, the selection depends on the output generated by
the meter.

If the meter provides a pulse train representing the volume increment, the
MVI56E-AFC should be configured as linear with the primary input set to Pulse
Count.

If the meter provides instantaneous flow rate, the MVI56-AFC should be
configured as differential with the primary input set to Flow Rate.

contain a number of items with different representations.

In the first row, the first position indicates whether the register is a Holding
Register (H-) or an Input Register (I-), the second position represents the
register (8000). The third position indicates high order bytes (H), low order
bytes (L), multiple registers (*), and a plus sign (+) indicates that there are
two registers (used for 32-bit quantities, i.e., long integer and floating point
elements).
If SHOW BITS is checked, a number in the third position is the bit number. For
Datum Type “String”, each register holds two characters.

Configure the overall settings for the site. The Site Configuration dialog box is
where you assign the settings that apply to the entire project.

 Project name
 Modbus slave addresses
 Memory allocation
 Port configuration and mapping
 Site options and status

You can also obtain the MVI56E-AFC firmware version from this window.

Accessing Site Configuration Parameters

From the Project menu, choose SITE CONFIGURATION.

ProSoft Technology, Inc. Page 23 of 149
October 2, 2018

Configuring Site Parameters MVI56E-AFC ♦ Version 4.04

Parameter

Description

Site Name

Enter a site name. This parameter identifies the site (1 to 64
characters). The default is “AFC Flow Station”. Edit this if needed.

Project Name

This parameter allows an external application such as EAFC
Manager to synchronize its database with the database resident in
the module. Default is "MVI56E-AFC".

Primary and Virtual Modbus
Slave Address

If you plan on setting these parameters, please refer to the MVI56E-
AFC Reference Guide for additional details.

End of Day Minute

This parameter sets the minute of the day when the daily archives
are created. The default value of 0 (zero) creates the daily archive at
midnight. Valid values are between 0 and 1439. This moment is
relative to the module’s wallclock, which is expected to be UTC time.

Important: The End of Period (End-of-day minute and End-of-hour
minute) settings are global settings, unless these settings are set by
meter on the Meter Configuration page. If these parameters are set
per meter, and enabled under control options, the options specified
per meter take precedence over the same settings on the Site
Configuration page.

This action opens the Site Configuration dialog box.

MVI56E-AFC ♦ Version 4.04 Configuring Site Parameters

Parameter

Description

End of Hour Minute

This parameter sets the minute of the hour when the hourly archives
are created. The default value of 0 (zero) creates hourly archives at
the top of each hour. Valid values are between 0 and 59. This

moment is relative to the module’s wallclock, which is expected to be

UTC time.

Important: The End of Period (End-of-day minute and End-of-hour
minute) settings are global settings, unless these settings are set by
meter on the Meter Configuration page. If these parameters are set
per meter, and enabled under control options, the options specified
per meter take precedence over the same settings on the Site
Configuration page.

Barometric Pressure

This parameter sets the barometric pressure used on the module
calculations. The module expects each meter's pressure input to be
in gauge units. Because the AGA8, AGA3, and some API2540
calculations require the pressure of the fluid to be in absolute units,
the module adds barometric pressure to the gauge pressure in order
to obtain the absolute pressure.

The calculation assumes that all meters measured by a single
MVI56E-AFC are located at the same site and have the same
barometric pressure.

ProSoft Technology, Inc. Page 25 of 149
October 2, 2018

Configuring Site Parameters MVI56E-AFC ♦ Version 4.04

Parameter

Description

Event log lockable

If clear, the event log behaves as a FIFO buffer; a new record
overwrites the old one even if the overwritten event has never
been downloaded, in which case, the event is permanently
lost. If set, and the log is full with never downloaded events,
then the log is locked. Controllable events (changes to most
datum points) are not allowed to occur. Non-critical, non­controllable events (e.g. checksum alarms) are discarded and
are permanently lost, and critical non-controllable events (e.g.
PLC mode change) are written as usual and the overwritten,
never downloaded events are permanently lost. A locked log
must be downloaded to unlock it for normal behavior.

Barometric pressure in psia

If set, the barometric pressure will be expressed in psia units,
otherwise it will use kPaa.

Configuring Site Options

The Site Options dialog box opens when you click the SITE OPTIONS field in the
Site Configuration dialog box. Not all options are available unless other

parameters and options are selected during the configuration process.

Page 26 of 149 ProSoft Technology, Inc.

MVI56E-AFC ♦ Version 4.04 Configuring Site Parameters

Configuring Pass-thru Options

The Pass-Thru feature can be used for delivering data written by Modbus
packets directly to the PLC logic, bypassing the MVI56E-AFC’s Modbus
database. For details on configuring this option, please refer to the MVI56E-AFC
Reference Guide.

The module supports the Modbus Pass-Thru feature for write commands. When
the pass-thru region in the virtual slave is properly configured, all Modbus write
commands pointing inside that area will be handled by ladder logic using the
Modbus Pass-Thru function block.

Viewing Site Configuration Status

This section of the Site Configuration screen is used to provide Site status
information. Site status features are discussed in the MVI56E-AFC Reference
Guide.
