Abstract
An apparatus performs methods for device diagnostics based on signals from digital outputs. The apparatus includes an input/output module with a digital output module to be coupled to a device. The input/output module measures one or more characteristics of a digital signal provided by the digital output module, where at least one of the one or more characteristics of the digital signal is associated with an output current of the digital output module. The input/output module also performs one or more diagnostics using the one or more measured characteristics of the digital signal.
Claims20
A method comprising:
- measuring one or more characteristics of a digital signal provided by a digital output module, the digital output module coupled to a device, at least one of the one or more characteristics of the digital signal associated with an output current of the digital output module;
- and
- performing one or more diagnostics using the one or more measured characteristics of the digital signal.
An apparatus comprising:
- an input/output module comprising a digital output module configured to be coupled to a device, the input/output module configured to:
- measure one or more characteristics of a digital signal provided by the digital output module, wherein at least one of the one or more characteristics of the digital signal is associated with an output current of the digital output module;
- and
- perform one or more diagnostics using the one or more measured characteristics of the digital signal.
A non-transitory machine-readable medium encoded with executable instructions that, when executed, cause one or more processors to:
- measure one or more characteristics of a digital signal provided by the digital output module, wherein at least one of the one or more characteristics of the digital signal associated with an output current of the digital output module;
- and
- perform one or more diagnostics using the one or more measured characteristics of the digital signal.
