RealFLO Application Changes

• RealFLO is corrected to ensure flow computer, flow run and MVT configuration dialogs are not accessible when RealFLO is in the Update Readings mode.
• RealFLO corrected to ensure all serial port settings are correctly written to the flow computer. The parity and TX flow settings were not correctly written if they were changed from the default values.
• The Current Readings view in Maintenance Mode is modified to ensure the view fits completely on the PC screen. In the initial RealFLO 6.0 release view did not completely fit on the PC screen.
• The New File wizard in the Maintenance Mode is corrected to ensure that the configuration file can be written to a flow computer with an existing configuration. The wizard would present a dialog to confirm that the user wanted to write the configuration but could continue depending on the user response.
• The New File wizard is corrected to ensure changes made in the offline MVT configuration do not cause RealFLO to crash.
• CFX export functionality is corrected to ensure that 24 hourly records, for each day, are exported when the Export One Record Per Hour option is selected. The hourly records were not being sorted correctly before exporting in the initial release of RealFLO 6.0. This could result in fewer than 24 records or more than 24 records being exported.
• The Maintenance Mode screen displays correctly regardless of the windows font size used. The Maintenance Mode screen would not display correctly if large font size were selected.
• The View Current Readings wizard is corrected to ensure the wizard does not get stuck at any step. The wizard could get stuck if the configuration in the flow computer was different than the configuration in RealFLO.
• Enron Modbus interface is corrected to ensure that all alarms are included and that all alarms contain the correct values. Some NX-19 and AGA-8 alarms were missing and some alarms were incorrectly mapped resulting in bad values.
• The H2O at 60F units have been added to the selection for Differential Pressure units when a 3095 transmitter is configured.
• The Search for Transmitters dialog is corrected to ensure the Search LAN parameters; IP Address, Protocol and Timeout are not greyed out when the dialog is opened and the Search LAN button is selected.
• The New File wizard is corrected to allow the offline configuration of 4102MMTs using a LAN connection. A number of errors would occur when a LAN connection was selected, including incorrect device type and device address.
• RealFLO is corrected to ensure the Differential Pressure Low DP Cutoff is properly checked for a valid entry. Incorrect entries could be entered and in some cases written to the flow computer.
• The New File wizard is corrected to ensure user entries are not replaced with default values when moving forward and backward through the wizard steps. The incorrect, default, values would be written to the flow computer at the completion of the wizard.
• RealFLO is corrected to ensure that when the load flow computer command is cancelled during the load the user is able to load a flow computer after the cancellation. When a load was cancelled RealFLO would not display the Load Flow Computer step in a subsequent New File wizard.
• RealFLO now checks the version of the flow computer when the Force button is selected. If the flow computer does not support forcing, the error message "The Flow Computer does not support forcing" is displayed and the Force wizard is not opened.
• RealFLO is corrected to ensure an error is not generated during the Calibration Report Comments step in the Calibration wizard. In some cases the Calibration Report document object did not correctly read the Windows Registry settings.
• The error message displayed when AGA-8 gas components do not add to 100 percent or 1.0000 is modified to be more informative. The user is now prompted as to what to do to correct the error.
• RealFLO correctly displays the Static Pressure units when a 3095 transmitter is configured for gage pressure. In some dialogs the units were displayed as psia or psi. All dialogs now display the correct units.
• The New File wizard now correctly displays the psia or psig units on the Static Pressure Limits dialog.
• RealFLO checks for valid entries in the Atmospheric Pressure entry in the Static Pressure dialog when gage pressure is selected. An error message is displayed if the atmospheric pressure is outside the valid entry values for the unit type.
• RealFLO corrected to ensure that all values in the actual column are copied to the proposed column when the Copy to Actual to Proposed button is selected. Not all actual values were being copied to the proposed values.
• The Export CFX command now correctly exports logs based on the CFX Export Options selected. Exported logs were not exported to the file and location selected.
• The New File wizard is corrected to ensure that users cannot inadvertently miss wizard steps.
• RealFLO is corrected to ensure the run configuration settings are saved to the MVT configuration when the run input type is selected as MVT. Some settings were not transferred from the run configuration to the Measured Variables page in the Add/Edit Transmitter Settings dialog.
• RealFLO is corrected to ensure default values are not used when a Template is used in the New File wizard. Values used in the creation of the template file are used in all cases where the template is used to create a new file.
• RealFLO corrected to not display incorrect error messages when communication errors are detected. In some cases an Internet Connection Error would be displayed when a serial connection was being made.
• RealFLO corrected to ensure the New File wizard does not write an MVT configuration when there is no MVT used in the run configuration. The New File wizard would incorrectly write an MVT configuration resulting the flow computer trying to poll for MVT data.
• The New File wizard is corrected to ensure users cannot get stuck or be unable to navigate forward and backward in the Perform Operations dialog or Connect to Flow Computer dialog. Navigating to or from these dialogs would sometimes result in the user being unable to navigate out.
• The default Timeout value is set to 1000ms whenever a 4202GFC or 4202GFC-DS controller type is selected.
• RealFLO correctly opens files created in older versions of RealFLO. Some older files were generating errors when opened in RealFLO 6.01.
• RealFLO correctly populates the Setup dialog information when the Read Configuration wizard is executed. In some cases the firmware type was incorrectly displayed as TelePACE when ISaGRAF firmware was installed.
• Double clicking of the Flow Run Configuration in the menu tree opens the Configuration dialog.
• The correct run number is displayed in the calibration report for a meter run. The Current Readings As Found \and the Current Readings As left would always display Run 1.
• RealFLO is corrected to ensure a new flow computer is not written when a user does not have the configuration file with the correct Accounts. An error message is displayed when the user, without the correct account, attempts to connect to a flow computer.
• RealFLO is corrected to ensure all configuration information is read from the flow computer when the Read Configuration is selected. Not all transmitter information was read previously.
• RealFLO corrected to ensure offline MVT configurations can be written to the flow computer in all cases.
• The flow computer correctly accepts changes to the Log Low Flow Events that are written to it. The flow computer would not change the setting that was written.
• The flow computer is corrected to start a new hour for a fun only when changes affecting that run are made. Some changes to one run would cause a new hour to be created for another run.
• The flow computer corrected to export a single Power On and Power Off alarm when they occur. Multiple alarms were being exported for Power On and Power Off.

Firmware Version Requirements

Since installation of the new flow computer software will result in removal of all existing flow history in the flow computer, the additional overhead of installing the latest firmware is minimal. It is recommended that the firmware in the target controller be upgraded to the latest version.
The latest version of firmware at the date of this notice is:

• For SCADAPack 32 and SCADAPack 32P target controllers firmware version 1.60.
