AFC Manager

PSW-AFC

The AFC Manager is an easy-to-use Windows 98/NT/2000/XP based configuration, reporting, and monitoring tool provided with the AFC modules. Project configurations may be uploaded, downloaded and saved to the PC under user selectable file names.

• Allows the user to monitor each meter run (flow rates, accumulator values and other calculation results). All alarm data is displayed on the screen.
• Allows user to download and view the archives and events.
• Allows the user to perform an Audit scan. This shows the process input variables and calculation results as "snapshots", allowing verification of the calculations
• Provides easy access to the Primary Modbus Slave data (130.000 registers) and Virtual Modbus Slave data (20.000) registers.
• Provides the ability to perform data remapping to optimize the polling of data
• An optional password protects changes to certain configuration parameters and reading of critical meter data

Features and Benefits

The AFC Manager allows you to perform the following tasks with your AFC modules:

• Manage multiple AFC modules with multiple firmware revisions
• Configure project parameters (site configuration)
• Configure the port communication parameters
• Remap registers from the primary slave to the virtual slave. Modbus master interface allows easy access to primary and virtual database.
• Configure meter channels
• Enable and disable the meter channels
• Set the module passwords
• Keep track of configuration changes
• Monitor the meter operation
• Perform an audit scan
• Configure the archives
• Monitor the archives
• Monitor the events

The AFC Manager can be used to configure the AFC module project parameters (Site Configuration) and each meter (Meter Configuration).

Once your project is up and running, you can also use the AFC Manager to monitor each meter run (Meter Monitor), archives, and events.

AFC Version 2.05 Update Notice

If your module measures liquids, please read this notice before upgrading from version 2.04 (or earlier) to 2.05 (or later).

For compliance with new measurement standards, the AFC version 2.05 has introduced several new liquid product groups. In particular, the two non-refined liquid product groups of version 2.04, which covered the entire density range of crudes and NGLs, have each been split into two separate product groups, one for the higher density range of crudes and the other for the lower density range of NGLs. If your module has meter channels configured for either "Crude, NGL" or "Oil-water emulsion", you should decide before upgrading the firmware the new product group (light or heavy) to which each such channel should be assigned. This assignment will be performed during the upgrade process and will preserve all other configuration and historical records including accumulator values and archives, in contrast to changing a product group after the upgrade which resets the meter configuration and erases all historical records. Meter channels configured for "Gas" or "Refined products" are not affected.

AFC Manager exhibits the same behavior when converting a project between versions 2.04 (or earlier) and 2.05 (or later).

The criterion for assigning the new product group depends on the density units and the Default Reference Density, as detailed in the following tables:

Density Units = kg/m3

Density Units = Rd/60

Due to roundoff error of numeric conversions, a Relative Density very close to the cutoff value of 0.6100 may cause the module to assign the new product group opposite to the one that was intended. Before upgrading, change the Default Reference Density to a number significantly different from 0.6100, such as 0.6110 (to target Crude) or 0.6090 (to target NGLs). You may change it back to the correct value after the upgrade

Density Units = API Gravity
