Variable

With a Variable Node, you can set one or more Variables to Expressions that are evaluated before. For Boolean Variables, you can decide if you want to set an Expression or toggle a switch.

This Node is not only useful for evaluating Expression and save its value, but also to interact with the periphery as Variables can be bound to it (e.g. to I/Os or Modbus/TCP).

For every Variable that you set, you can additionally define a delay which causes the Robot to wait before it executes the next command. This is useful e.g. if you want to trigger a vacuum gripper and you'll have wait until the vacuum is properly created.
