plcgeneraterunnertb

Generate L5X test bench code for specified AOI Runner block and AOI name

Syntax

TbCode = plcgeneraterunnertb (runnerBlk)

Description

TbCode = plcgeneraterunnertb (runnerBlk) returns the generated test bench code for the AOI runner block of the ladder diagram model. Open or load the Simulink^® Ladder Diagram model first.

Examples

Generate Test bench for AOI runner block

The following example demonstrates how to import a simple ladder diagram from an L5X file (simpleXIC.L5X) into the Simulink environment and generate test bench code for it. The ladder L5X file was created using RSLogix™ 5000 IDE and contains an AOI named simpleXIC with contact and coil representing a switch and a light. The following is a snapshot of the ladder structure.

Use the plcladderimport function to import the ladder into Simulink.

[mdlName,mdlLib,busScript] = plcimportladder('simpleXIC.L5X',...
'OpenModel','On','TopAOI','simpleXIC')

The imported model contains an AOI Runner block named simpleXIC_runner, followed by a Ladder Diagram Function (AOI) block named simpleXIC.

Add Signal Editor input block, Scope and output ports as shown.

Modify the Signal Editor input to mimic a switch operation as shown.

Generate test-bench for the Ladder Diagram model.

Tbcode = plcgeneraterunnertb('simpleXIC_runner/simpleXIC_runner')

Tbcode =

  1×1 cell array

    {'C:\runnerTB\simpleXIC_runner.L5X'}

If the test-bench code generation completes with no errors, a test-bench file simpleXIC_runner.L5X is created. The generated AOI test bench file can be verified on Rockwell Automation^® IDE.

Note

Test-bench generation for ladder diagram models containing timer blocks such as TON, TOF and RTO fails. To generate test-bench code for these models, modify the ladder diagram structure while maintaining the logic.
