ControlWave Gas Flow Computer (GFC Plus) Instruction Manual (CI-ControlWave GFC Plus)

Revised Feb-2013 Operation 4-3

4.2.2 Changing Port Settings

You change port settings (baud rate, port type, IP address, and so on)

using the Flash Configuration utility.

You must establish communications with the ControlWave deviceusing

NetView, LocalView, or TechView before you can run the Flash

Configuration utility.

Note: For detailed information on using the Flash Configuration utility,

see Chapter 5 of the OpenBSI Utilities Manual (D5081).

Caution

When you change the baud rate for a port, the baud rate changes as

soon as you write the flash file changes to the RTU, and do not require

a reset. For this reason, you should not change baud rate for the active

port on which you are communicating, or communications will

immediately stop due to the baud rate mismatch between the PC port

and the controller port. If this happens accidentally, you can use CPU

switch settings as discussed in the notes in Section 4.2.1 to restore

defaults and re-establish communications.

4.2.3 Collecting Data from the ControlWave GFC Plus

OpenBSI utilities such as DataView, Data Array Save/Restore and

Harvester allow you to collect real time data (values of variables, array

values, alarm messages) and historical data (audit records, archive files)

from the ControlWave. See the OpenBSI Utilities Manual (D5081) for

details. SCADA software such as OpenEnterprise can then present this

data to an operator in the form of graphical displays and reports.

4.3 Creating and Downloading an Application (ControlWave Project)

Most GFC Plus users purchase the ControlWave gas flow measurement

application (ControlWave project) which ships pre-installed in the GFC

Plus when it leaves the factory.

You can, however, create your own project using PC-based

ControlWave Designer software. Instructions for creating a

ControlWave project are beyond the scope of this manual. Please refer

to the following sources for information:

 Getting Started with ControlWave Designer (D5085)

 ControlWave Designer Programmer’s Handbook (D5125)

 ControlWave Designer online help

You must connect the GFC Plus to a PC running ControlWave Designer

software and OpenBSI software.

Note: You can download an application either from ControlWave

Designer or from the OpenBSI 1131 Downloader.
