4 Testing the Project

4.1

The material supplied with ProTool contains a simulation program with which a project

can be tested on the configuration computer without needing to connect a PLC and

operating unit to it.

The simulation program

• modifies the value of configured tags in a definable way, e.g. incrementally,

decrementally, sinusoidally, randomly or via shift bits,

• sets bits in the area pointers for event and alarm messages, thus triggering

configured messages on the operating unit.

A condition for performing the simulation is that the simulation program has been

installed on the configuration computer.

Example: Manipulating the input/output field tags

• Save the project using the icon depicted

• Start the simulation program by clicking on the icon depicted directly from the

configuration software which is running

• Select the tags from the simulation table under "Tags" whose values are to be

manipulated, in this case "VAR_1"

• Enter the value "1.0" in "Write Cycle"

• Select the "Sinus" option in "Simulation"

• Enter the value "0" in "MinValue"

• Enter the value "100" in "MaxValue"

• Enter the value "10" in "Interval"

• Activate the "Start" checkbox to start the simulation

• During the simulation, the various tag values can be observed in the input/output field

• Deactivate the "Start" checkbox to stop the simulation of the respective tags
