Numerous system variable are maintained in

ControlWave and the Designer System Variable

Wizard gives the user access to them by simply

selecting those desired in the Wizard menu.

System variables are used for:

Control start up and power up execution and

control

Monitoring the efciency of task execution and

start up

Accessing the system date and time

Viewing diagnostic information about the

communication ports

A system variable is also available to provide a

port data line monitor. By viewing the variable, an

engineer can view the communication message

stream through the port. This is an extremely power-

ful feature available to those familiar with data line

monitor capability.

On-line Program Debug Tools

No matter how experienced the engineer, there is

always a need for powerful software debug tools.

ControlWave Designer offers a comprehensive set

of on-line tools to help you test, analyze and trou-

bleshoot your application program. Real-time data

values and program execution are displayed for all

ve languages.

The Variables Cross Reference list contains all

variables, function blocks, actions, transitions,

steps, jumps, labels and connectors which are used

within the current project. It is a helpful tool for de-

bugging and fault isolation.

The Logic Analyzer is a powerful tool for recording

values of variables over a certain time interval. They

are displayed graphically in the Logic Analyzer win-

dow. All recorded values and settings of the Logic

Analyzer are stored automatically with the project.

The Watch Window can be used to collect vari-

ables from different worksheets to gain an under-

standing about how these variables work together.

In addition you can use the watch window to force

and overwrite variables.

•

Breakpoint, Single Step and Single Cycle pro-

gram execution provides a step and trace function

that is extremely useful for program debugging.

These functions allow you to continue the program

execution line by line after a breakpoint has been

reached.

Power Flow

For graphical worksheets, IL and ST worksheets,

you can switch from the Variable Status to the Ad-

dress Status with Powerow and vice versa. Pow-

erow displays which program parts are actually

executed and which ones not. This is useful for

debugging worksheets with conditional jumps.

I/O Simulator

The ControlWave Designer I/O Simulator allows

the Application load program to be tested on a PC,

with simulated analog and digital inputs and out-

puts.

The I/O Simulator utilizes the identical real time

operating system used in the ControlWave unit; this

allows initial I/O testing and debugging to be per-

formed in a safe, isolated environment, without the

need for a running ControlWave unit and process

I/O boards.
