Select Program➔ Program Call Instruction to add a call to a sub program from the current program.
By default, this is a blocking call to a specific program. However, it is possible to switch to Insert Code to enter code specific at the location of this instruction. This might be useful for a specific application and a specific controller.
Switch from Program Call to Start Thread to provoke a non-blocking call to a sub program. In this case, the controller will start a new thread. This option is only available for certain controllers and only works for specific operations.
