All I/O devices must be derived from CogIODevice.

CogIODeviceList holds all I/O device objects that can be found in the system. However, this class can be used to add, remove or return a reference to the device object. See CogJobManager IODeviceList for getting references to devices in the system. Note: CogJobManger should only instantiate this class.

This class is used to hold a collection of CogIODiscreteDataItems to be used to program physical output lines.

This class is used to describe which line should be programmed to what value

Base class for all Cognex discrete I/O.

This class exists solely to allow accessing input delegates via an indexed property.

This class holds a discrete I/O line, a tool's property used to collect the result, and a boolean flag to indicate whether the Warning result must be treated as Reject or Accept. The result collected from this tool's property is sent to the I/O line. This class is not thread-safe.

CogIODiscreteElementList contains a list of CogIODiscreteElement. This class is not thread-safe.

CogIODiscreteInfo describes the type of Cognex frame grabbers I/O.

This is a base class which contains a device name. CogIOSerialInfo, CogIOTCPIPInfo, and CogIODiscreteInfo must derive from this class. XXXDeviceInfo classes are used to describe a device type. This infomation is later used for retrieving an actual device object from CogJobManager or for sending output data.

CogIOInfoList includes all CogIOInfo derived objects. Each job holds an instance of CogIOInfoList.

Input event args. When I/O device generates a input event to CogJobManager, CogIOInputEventArgs has to be passed to inform the input contents.

This class is used to capture Run Once, Run Continuously, Clear To Send, Online, and EStrop input commands.

This class defines all the input commands that are supported by CogJob.

This class encapsulates all characteristics of a single instance of the Measurement Computing PCI-DIO24/S digital input/output board.

CogIOOutputData has to be passed to write method of CogIODevice. CogIOOutputData Includes the actual output data for device.

This class is used to generate data ready, move part, acq complete, etc., signals.

This class defines all the output commands that are supported by CogJob.

Provide information for an IO stream elemen.

Provide an abstraction for formatting a property value.

Cognex internal use only

Prototype for a delegate function to be called when an input line changes state.

List of input commands that the user is able to set for each job.

Indicates polarity of the line.

Each port on the Measurement Computing PCI-DIO24/S board may be configured for either input or output. This enumeration helps you specify which.

The CogIOMCBPortNumberConstants are used to refer to a specific port on the Measurement Computing PCI-DIO24/S board. There are four ports: A, B, CL, and CH. Ports A and B are each 8 bits, while ports CL and CH are each 4 bits. If you are using the 8-line version of the Measurement Computing PCI I/O board, its lines are presented through ports CL and CH (lines 16 through 23).
