Use Run Mode Change
Run Mode Change allows the user to make small changes to the logic of a running project and
immediately testing it out on the controller, without having to go into Program mode or
disconnecting from the controller.
The following sample project guides you through the creation of a simple application for a
Micro850 controller without any plug-in modules, and how to use the Run Mode Change
feature.
Create the Project
1. Create a new project for a Micro830/Micro85/Micro8700 controller without any plug-ins.
Observe that the controller is disconnected.
2. Right-click Programs and select Add
