Configuring a software controller

3.1

Overview of software controller

For the configuration of a software controller, you need an instruction with the control
algorithm and a technology object. The technology object for a software controller
corresponds with the instance DB of the instruction. The configuration of the controller is
saved in the technology object. In contrast to the instance DBs of other instructions,
technology objects are not stored for the program resources, but rather under CPU >
Technology objects.
