GPI/GPO Operators in VisualApplets

Using VisualApplets, you can design your own, application-specific trigger system. You can, e.g., determine which signal is sent or received by which individual physical input/output pin.

In VisualApplets, you have two operators available to wire up an individual pin with your applet design:

Using multiple instances of the GPI and GPO operators in a design

Each trigger IN / trigger OUT pin you want to use on the Front GPIO or the GPIO socket you have to interconnect with an instance of a GPI/GPO operator.

 

GPI and GPO Operators

 

Since operator GPI functions exactly as operator GPO, in the following both operators are described together.

   
  1. Double-click on the operator icon in your design to open the Module Properties window.

The Module Properties window opens:

As you see, the operator has two parameters:

Parameter ConnectorType allows you to define which connector (Front GPIO or GPIO) you want to address. Parameter Pin_ID allows you to define which individual pin on the selected connector you want to address.
