Setting Up Device Data:The device integration functionality enables you to read data directly from devices into the application. Data is collected directly from the point of generation of the data into the application. The device integration feature enables the collection of the shop floor data directly from active devices that are online and generating current data. Device Integration eliminates the need for manual input and associated errors with data entry.
Device Integration enables:
Shop floor device data collection in MES transactions. See, Moving and Completing Assemblies, and Quality Display Modes in Oracle Manufacturing Execution System for Discrete Manufacturing User's Guide..
Shop floor device data collection in Standalone Quality Workbench. See,Collecting Device Data in Standalone Quality Workbench.
The device integration feature is available only if Oracle Manufacturing Execution System (MES) for Discrete Manufacturing is installed. Device integration in MES for Discrete Manufacturing and Quality Workbench is carried out through third party OPC Servers that serve as middleware connecting the sensors to the enterprise application. The data will be pulled from the third party OPC server on a fixed schedule. The application will read the latest data from the OPC server. However, data based on a user request or an event cannot be retrieved from the OPC server or devices.
Device integration feature captures numeric, date and character type data only which can be mapped to a string type data. Videos or graphics or any other type of data that is not passed on as a string cannot be captured. The application will convert the data type to the appropriate data type as per the setup of the collection element. The numeric precision of the data is determined by the OPC Server. You can also get a time stamp of the data generation time by the device.
To use the device integration functionality:
Install Oracle Manufacturing Execution System (MES) for Discrete Manufacturing and enable the profile option WIP: MES for Discrete Manufacturing Install.
Follow the instructions from the OPC server provider and install and commission the third party OPC server.
Set up device data in Oracle Quality. See, Setting Up Device Data.
Set up collection plan elements as device enabled with the required device details. See,Defining Collection Plan Elements.
Setting Up Device Data:Use the Device Data Setup page to define the list of devices with proper device identification details. You can also use the search region in this page to query for existing devices. Search for existing devices using any combination of Device Name, Sensor Alias and Device Description values.
Note: Device integration is for active devices only that remain online continuously. This feature is not associated with passive devices that are activated on a need basis like triggering of an event.
Navigate to the Device Setup page. Click Add Another Row to add a blank row to define a new device.
In the Device Name field, enter the name of the device as it is defined in the third party OPC Server.
Note: The application does not validate the device details you enter during the set up. The Device name is used as entered. Should there be any changes, update the device details. If the device name is incorrect in the set up, a value from a wrong device is pulled or no value is received from the repository for the parameters to which the device name is associated and a message displays.
Enter a sensor alias in the Sensor Alias field. This can be any value that would denote the OPC server which connects to the device.
In the Device Description field enter a description of the device. Device description is a user-friendly name for the device. This name will be available in the Collection Plan definition form.
Note: The Sensor Alias and Device Name together must be unique as they identify the device. If you enter a value that is not unique, an error message will display and the data will not be saved.
In the Frequency of Pull field, you can optionally enter the frequency value in milliseconds. This is the frequency at which the application is configured to receive data from the OPC Server.
Enter the Elapsed Time in milliseconds, which is the cutoff time to decide whether a particular data is current or historic. If the data is older than the elapsed time, it will be considered as historic data and if the data is captured within this time frame then it is current.
Check the Manual Override option to enable manual override of the device data. If the checkbox is unchecked, you cannot override the data captured through a device manually. Note that the value in this check box only provides a default value at the plan level. This can be overridden by setup at the plan level. The value chosen here will default at the collection plan level.
Check the Enabled option. Only the enabled devices will appear in the list of values in the Collection Plan definition form.
Click on Apply to save the device setup.
After setting up the device data, associate the device in to the collection plan elements in the collection plan definition form. These collection plan elements can receive data from the shopfloor device in standalone Quality Workbench or in MES transactions if MES for Discrete Manufacturing is installed.
Note: You can also import data to the Device Data Setup page from the third party OPC Servers. To import data from the third party OPC servers, refer to the appropriate OPC server documentation for details.
