I have a FB (SmartLogic) with two boolean input variables and one output variable, but I want the output to depend of a parameter X too which i want to set during instantiation before the FB is called. Is that possible? And how do I do that?

  1. If you define X as global it will be accessible in your FB.
  2. You can pass X variable as another input parameter. Simply call FB after you initialize X variable.

You can initialize FBs variables with the FB_Init method.

In CoDeSys help there is information about this methods.
