Detailed information on the Flash Configuration Utility, and LocalView is included in
Chapter 5 of the Open BSI Utilities Manual (document # D5081). NetView is described in
Chapter 6 of that same manual. TechView is described in the TechView User’s Guide
(document# D5131).
Step 4. Create an Application-Specific Control Strategy in ControlWave Designer
At this point, you can create your application-specific control strategy using ControlWave
Designer. This involves opening a new project using the ‘CWMicro’ template, defining I/O
boards using the I/O Configurator, and creating a program using one or more of the five
supported IEC 61131 languages (FBD, ST, SFC, LD, or IL). Some of these languages are
text-based, others use graphical diagrams. The choice is up to you, depending upon your
particular application.
The ControlWave MICRO Quick Setup Guide (document # D5124) includes a simple LD
example. Additional examples are included in the manual, Getting Started with
ControlWave Designer (document # D5085). More detailed information about ControlWave
Designer and IEC 61131 is included in the ControlWave Designer Reference Manual
(document # D5088).
The ACCOL3 Firmware Library, which is automatically accessible through the template
referenced above, includes a series of function blocks which perform a variety of process
control and communication functions. These can be included within your program to
perform various duties including PID control, alarming, calculations, etc. Detailed
information about each function block is included in the ControlWave Designer on-line help
files.
On the variables declaration page(s) in ControlWave Designer, you will need to mark any
variable you want to make accessible to external programs, such as Open BSI’s DataView
utility, as “PDD”. Similarly, any variables which should be collected into a database, or
exported using the OLE for Process Control (OPC) Server must be marked as “OPC”.
Variables marked as OPC can be built into a text file by the OpenBSI Signal Extractor.
The text file can then be used in the creation of a database for human machine interface
(HMI) software such as OpenEnterprise or Iconics’ Genesis. These HMI software packages
require that the "Datatype conversion enable" option be selected when generating the
file using Signal Extractor. Information about the OpenBSI Signal Extractor is included in
Chapter 12 of the Open BSI Utilities Manual (document # D5081).
Once the program has been created, it is assigned to an executable task. The entire project
is then saved and compiled.
NOTE: From this point on, the order of steps may be varied, somewhat,
depending upon the requirements of the user's application.
Step 5. Create Application-Specific Web Pages (OPTIONAL)
ControlWave Express RTUs support a set of standard web pages for data collection
purposes and for access to communication statistics maintained in the controller.
Optionally, additional user-created web pages may be created to allow a customized
human-machine interface. A series of ActiveX controls for data collection and configuration
are provided on the OpenBSI CD which can be included as part of these user-created web
pages. For information on the ActiveX controls, see the Web_BSI Manual (document #
D5087).
