What is event in Capl?

CAPL – Communication Access Protocol Language is used by Vector tools like CANoe and CANalyzer. It is an event based language, that can be used for automating/semi-automating in a CAN environment. Its mostly like C with few changes. … This event takes place on clicking the stop button in CANoe/CANalyzer window.

What is System variable Capl?

CAPL Function Overview » General » putValue. System variables are widely used by CANoe components, many of them are generated automatically and can’t be edited. They belongs to a defined namespace. The values of sysvars are available only while measurement is running, so you don’t want to use them for e.g. UI-panels.

How do you call a function in Capl?
