Abstract
An output module includes multiple outputs, each output having switches, wherein the switches are configured such that a load is connectable between the switches, and a calibration unit configured to disconnect the load from the switches for a calibration period, monitor a behavior of the load while disconnected, and store samples of the behavior of the load. Further aspects of the present disclosure relate to a control system and a method for testing an output module connected to a complex load.
Claims14
An output module comprising:
- a plurality of outputs, each output comprising switches, wherein the switches are configured such that a load is connectable between the switches, wherein the load comprises capacitive and/or inductive characteristics;
- and
- a calibration unit configured to
- disconnect the load from the switches for a calibration period,
- monitor a behavior of the load while disconnected, and
- store samples of the behavior of the load,
- wherein a discharge of the load is monitored while disconnected from the switches, and
- wherein the samples include a discharge curve of the load.
A control system comprising:
- a processor,
- a power supply,
- an input module, and
- an output module comprising:
- a plurality of outputs, each output comprising switches, wherein the switches are configured such that a load is connectable between the switches, wherein the load comprises capacitive and/or inductive characteristics;
- and
- a calibration unit configured to
- disconnect the load from the switches for a calibration period,
- monitor a behavior of the load while disconnected, and
- store samples of the behavior of the load,
- wherein a discharge of the load is monitored while disconnected from the switches, and
- wherein the samples include a discharge curve of the load.
A method for calibrating and testing an output module comprising a plurality of digital outputs, each digital output comprising switches, wherein a load is connected between the switches, the load comprising capacitive and/or inductive characteristics, the method comprising:
- disconnecting the load from the switches for a calibration period;
- monitoring a behavior of the load while disconnected;
- and
- storing samples of the behavior of the load,
- wherein monitoring the behavior of the load comprises monitoring a discharge of the load while disconnected from the switches, and
- wherein the samples include a discharge curve of the load.
