Emerson Process Management ControlWave XFC - Manual (Page 19)

CI-ControlWave XFC Introduction / 1-5
function blocks accomplish various tasks common to most user applications including
alarming, historical data storage, as well as process control algorithms such as PID
control.
• The OPC Server (Object Linking and Embedding (OLE) for Process Control) allows
real-time data access to any OPC [Object Linking and Embedding (OLE) for Process
Control] compliant third-party software packages.
• A set of ControlWave XFC web pages is provided to set configuration parameters for
the standard gas flow measurement project, running in the unit. These web pages use
Bristol Babcock-specific ActiveX controls for retrieval of real-time data values and
communication statistics from the unit. The ActiveX controls are compatible with
Microsoft® Internet Explorer. Alternatively, developers can place the ActiveX controls
in third-party ActiveX compatible containers such as Visual BASIC or Microsoft® Excel.
• User-defined Web Pages – Users can place the same ActiveX controls into their own
web pages to provide a customized human-machine interface (HMI) to the Control-
Wave XFC.
• Flash Configuration Utility – Parameters such as the BSAP local address, IP ad-
dress, etc. are set using the Flash Configuration Utility, accessible via Open BSI
LocalView or NetView. The ControlWave XFC ships with a standard Flash Con-
figuration Profile (FCP) file, with default configuration parameters already set.
1.3 PHYSICAL DESCRIPTION
ControlWave XFC gas flow computers are comprised of the following major components:
• Housing with LCD Display (Section 1.3.1)
• Function Module (Section 1.3.2)
• CPU Board Assembly (Section 1.3.3)
• I/O Board Assembly (Section 1.3.4)
• Terminal Plate (Section 1.3.5)
ControlWave XFCs can be factory configured with the following options:
• Multivariable Transducer (MVT) or Gage Pressure Transducer (GPT) (Section 1.3.6)
• RTD Probe (Section 1.3.7)
1.3.1 Housing
ControlWave XFCs are housed in an explosion proof enclosure (case) that is cast from 356
aluminum. External dimensions (are approximately 6.16” high, by 5.00” wide, by 6.19”
deep. When present, the Multivariable Transducer adds 3.02” while the Gage Pressure
Transducer adds 1.72” to the height of the unit. The housing consists of the main body and
two threaded covers, i.e., the Front/Display Cover and ther Rear/Wiring Cover.
The Front/Display Cover provides a viewing window for the LCD display. In normal
operation, the display remains running after the unit has been configured and placed into
service. Acess to the Terminal Plate is gained by removing the Rear/Wiiring Cover.
