1-6 / Introduction CI-ControlWave EFM
ControlWave EFM units provide an ideal platform for remote site automation,
measurement, and data management in the oil and gas industry.
The control strategy file created and downloaded into the controller is referred to as a
ControlWave project. The ControlWave EFM ships from Bristol Babcock with a
standard ControlWave project, pre-configured for gas flow measurement, already loaded
and ready to run.
The ControlWave programming environment consists of a set of integrated software tools
which allow a user to modify the standard gas flow measurement project to fit the needs of
their own particular application, as well as to create, test, implement, and download a
different ControlWave project, if desired.
The tools that make up the programming environment are:
• ControlWave Designer load building package offers several different methods for
generating and debugging control strategy programs including function blocks, ladder
logic, structured languages, etc. The resulting process control load programs are fully
compatible with IEC 61131-3 standards. Various communication methods as offered,
including TCP/IP, serial links, as well as communication to Bristol Babcock’s Open BSI
software and networks
.

• The I/O Configuration Wizard, accessible via a menu item in ControlWave Designer,
allows you to define process I/O modules in the ControlWave and con-figure the
individual mapping of I/O points for digital and analog inputs and outputs.
• The ACCOL3 Firmware Library which is imported into ControlWave Designer,
includes a series of Bristol Babcock specific function blocks. These pre-programmed
