WizPLC
Easy to learn, implement and maintain
The debugging functions of WizPLC help users quickly locate errors in
their program. WizPLC allows users to set breakpoints anywhere in the
program. When execution has stopped, the user can examine all program
data at this point. The single step function allows the user to check
the program logic step by step.
As an additional debugging tool, WizPLC allows the forcing of program variables and I/O to certain values. Flow control enables the user to check which program lines are performed and shows the user the value of each variable used in this line as the code was executed.
In Online Mode, the visible variable declarations are followed by the
monitoring of current values in the controller. In simulation mode, the
user program runs without reading inputs or writing outputs. All online
functions can be used in this mode, allowing the user to test the program
logic at their desk without any hardware.
When all errors are removed, users can switch to simulation mode, log into the simulated controller and load their project into the controller. WizPLC is then in online mode.
Breakpoints help debug complex logic
WizPLC allows users to set breakpoints anywhere within the program. When
a breakpoint is reached, the program execution is suspended, allowing the
user to view all current program data, including variable values. The
user can then command the program to continue. This ability to look inside
the program makes it much easier to understand and debug complex logic
sequences. This is especially true for high-speed logic, which is too
fast for the normal monitoring tools to display.
Breakpoints can be set in any of the WizPLC programming languages. Combined with other debugging tools such as Single Step and Single Cycle users can then control and monitor programs in a way that is impossible in traditional proprietary PLCs.
Sampling trace lets you trap events
The Sampling Trace function allows the user to record the progress of
program values, dependent on a trigger event. The trigger can be the falling
or rising edge of a Boolean variable. WizPLC enables the user to trace
up to 500 values of up to 20 variables. Sampling Trace allows the user
to trace the values of variables and to display the values as a curve.
Flow control
With the snap shot, the user can display the values of variables during
a cycle by defining a snap shot area and making a snap shot. Then, any
variable in a line in the snap shot area is monitored with the current
value at the execution of the line without halting execution.
Online changes prevent downtime
The WizPLC development studio and runtime logic engine are closely integrated
so that program changes can be made online, without having to shut down
the running program. This prevents downtime during troubleshooting and
debugging.
