4、itemsFailure Results Queue: Failures as indicated by Application Properties Discrete I/O Through QuickBuildIn order for QB to generate I/O signals, enable I/O settingsOpen the Communications ExplorerCommunications ExplorerFirst you need to add the appropriate deviceGo into the created folder to gain

5、 access to the individual linesCommunications ExplorerUsage - Then you would set the lines to be input or output.The module that you use will dictate the polarity available for the linesOwner Select which job (or the application as a whole) that controls the signalCommunications ExplorerField Select

6、 the appropriate parameter or tool result Pulse Width and Polarity Defines the amount of time the pulse is on as well as whether this is high or low (for connecting with NPN or PNP devices)Check ConfigurationTo make sure the configuration is correct click on “Configuration Checking”.This will check
