LabVIEW State Machine Module

[Michael.Proctor]

Hi,

Has anyone used with succes the LabVIEW State machine module to develop a cRIO application.

How accessible is the code generatored to modifiy by manual means the, I presuem labview code that is generatored.

thanks

Hi Michael,

From your post, I wasn't sure if you simply wanted to code an embedded state machine in a cRIO application, or you wanted to use the LabVIEW Statechart Module to create a cRIO application. The good news, is both of these options are a possibility. Take a look at the following links for more information about either method.

Hi Alex,

thanks for your reply.

My question was more towards, if you use the State Machine Module,

can you take the code generated from that module and modify it if necessary.

Just clarify the usage of State Machine here is not only the use of case statements as a programming method but also as a flow of nodes and edges to determine the control of an application depending on say, the robots present state... ie homed or not homed

Hi Michael,

You can certainly alter the code that the LabVIEW Statechart Module generates. It looks like the module simply creates a subVI in LabVIEW that performs the same functionality as the statechart. You can open this subVI and add any additional functionality you need or debug anything that doesn't perform correctly.
