What is the Virtual ControlWave?

The Virtual ControlWave is essentially a ‘software’ version of the ControlWave controller that
exists on your PC, instead of in a separate piece of hardware. It can do much of what a regular
ControlWave can do, however, it has no I/O hardware, and like the ControlWave Designer I/O
Simulator, it cannot store historical data (audit/archive) or run custom communication protocols.
It can, however, communicate with the OpenEnterprise Database.

The Virtual ControlWave includes a set of tools that allow you to take real-time signals from the
OpenEnterprise Database and bring them into a ControlWave Designer project. Once in
ControlWave Designer, calculations can be created using those signals. The project may then be
compiled and downloaded into the Virtual ControlWave, where it runs like any other project.
The results of the calculations are then stored back in the OpenEnterprise Database.

This mechanism allows you to perform extensive calculations using any ACCOL III or IEC
61131 functions and function blocks. This can be used, for example, to do gas calculations, on
data from multiple RTUs, which would have been beyond the scope of the OpenEnterprise
Calculation Server.

There are three main parts to the Virtual ControlWave:

• Virtual ControlWave Configuration Tool – Allows you to identify which signals from the

OE Database will be used in the Virtual ControlWave.

• Virtual Controlwave Statistics Tool – Displays current values of variables updated via the

Virtual ControlWave.

• Virtual ControlWave – The actual soft-ControlWave.

Before You Begin

In order to use the Virtual ControlWave, you must have the following software installed and
running:

• ControlWave Designer (Project used must include the IPC_40 resource)

• OpenEnterprise Server Version 2.53 Service Pack 1 (or newer). The OpenEnterprise

Database must be configured and running. NOTE: If you have Version 2.53 without
Service Pack 1, you must manually start Polyhedra DDE software for the Virtual
ControlWave Configuration Tool to function properly.

• OpenEnterprise OPC Server must be running, if not running automatically.

• Virtual ControlWave Software, including configuration tools.
