Abstract
An electronic valve controller for an open-loop and closed-loop control of a valve island includes four or eight valve disks having pneumatic valves configured to perform a motion task. Applications for the open-loop and closed-loop control of the valve island can be loaded onto the electronic valve controller. The invention further relates to a valve assembly, which is controlled in an open-loop and closed-loop manner by an electronic valve controller, to a corresponding method, and to a system.
Claims22
An electronic valve controller for an open-loop control and a closed-loop control of a pneumatic valve assembly configured to execute a pneumatic movement task, the electronic valve controller comprising:
- an application for the open-loop control and the closed-loop control of the valve assembly being loaded or loadable in an executable manner on the electronic valve controller to execute the pneumatic movement task.
A method for open-loop control and closed-loop control of a pneumatic valve assembly configured to execute a pneumatic movement task, the method comprising:
- reading-in the pneumatic movement task;
- automatically generating an executable program code for the open-loop control and the closed-loop control of the pneumatic valve assembly on the basis of recorded pneumatic movement task being accessible from a library of application objects;
- and
- loading the executable program code as an application in real time on execution units of the valve assembly.
A pneumatic movement control system for the open-loop control and closed-loop control of a pneumatic valve assembly for executing a pneumatic movement task, the pneumatic movement control system comprising:
- an editor configured as a user interface for recording the pneumatic movement task;
- a calculation unit configured to generate, on the basis of the recorded pneumatic movement task, an executable program code that is provided as an application;
- and
- at least one execution unit of a valve assembly configured to read-in and execute the application to control the valve assembly in at least one of:
- an open-loop manner according to the movement task, or
- a closed-loop manner on the basis of internal closed-loop control variables and external process signals.
