1-4 / Introduction CI-ControlWave Express
•
ControlWave Designer programming package offers several different methods for
generating and debugging control strategy programs including function blocks, ladder
logic, structured languages, etc. The resulting 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 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 configure 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-specific function blocks. These pre-programmed 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.
• Flash Configuration Utility – Parameters such as the BSAP local address, IP
address, etc. are set using the Flash Configuration Utility, accessible via Open BSI
LocalView, NetView, or TechView. The ControlWave Express ships with a standard
Flash Configuration Profile (FCP) file, with default configuration parameters already
set.
1.3 PHYSICAL DESCRIPTION
ControlWave Express RTUs are comprised of the following major components:
• Enclosure/Chassis (Section 1.3.1)
• RTD Probe (Section 1.3.2.1)
• CPU/System Controller Board (Section 1.3.2)
ControlWave Express RTUs can be factory configured with one or more of the following
options:
• Process I/O Board (Section 1.3.3)
• Keypad/LCD Display (1.5.2 & 2.4.5)
1.3.1 Enclosure/Chassis
ControlWave Express RTUs are housed in an enclosure that accommodates mounting to a
Panel or a DIN-Rail. External dimensions are approximately 10.75” long, by 5.56” wide, by
2.06” deep (without mounting brackets). The enclosure consists of two pieces, the removable
Card Edge Cover and the Main Mounting Chassis. Two Thumb Screws can be loosened to
facilitate removal of the Card Edge Cover, and thus accommodating all instrument field
wiring.
RJ-45 connector J2 on the CPU/System Controller Board accommodates either an optional
standalone dual line LCD display or optional 4 x 20 LCD display supported with either a 2-
button or a 25-button keypad. In normal operation, the LCD associated with a keypad will
turn off after the unit has been configured and placed into service while standalone LCDs
