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:
- Operator GPI (for trigger IN signals)
- Operator GPO (for trigger OUT signals)

Since operator GPI functions exactly as operator GPO, in the following both operators are described together. |
- 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:
- Pin_ID
- ConnectorType
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.
