Point Application Properties

Use the Application page to configure application-specific properties for a particular point. For example, they may be used by Service Monitoring Service points, Facility points, or OPCIS points. If they are not serving an application-specific purpose, they can be used to store extra attributes.

The names of these properties, except the Questionable/Verified Flags, are user-configurable. Be aware that the property names are service-specific. That means that they apply to all records in the service. To change the names of the properties, right-click in the service pane and click Configure Attributes. See Setting Default Point Configuration for information about configuring default attributes and descriptions for the points attributes.

Table driven fields
Table Driven 1	Click … to select or configure an entry. Default options include: OPCIS Ignore Unreliable Value (OPCBADIGNR) and OPCIS Store Unreliable Value (OPCBADSTR). The entry is from the TRS.CMT1 table. The Table Driven 1 field is used to indicate what to do with the value of an OPC tag with OPC Quality flags that indicate an error. The default behavior is to mark as unreliable and save the value from the OPC server. If set to OPCBADIGNR and an unreliable value is read, it will be discarded and the previous value is retained. If set to OPCBADSTR and an unreliable value is read, it will be stored. See OPCIS Groups for more information.	Blank
Table Driven 2	Click … to select or configure an entry. Default options include: OPCIS Sync IO via Cache (OPCSYNCCCH) and OPCIS Sync IO via Device (OPCSYNCDEV). The entry is from the TRS.CMT2 table. The Table Driven 2 field specifies whether the OPC server is to retrieve data from the cache or the device. This applies to all synchronous communication. This attribute provides the functionality of the OPC_SYNC_IO configuration file keyword at the group level. If set to OPCSYNCCCH, the OPCIS will sync IO via the cache. If set to OPCSYNCDEV, the OPCIS will sync IO via the device. See OPCIS Groups for more information.	Blank
Table Driven 3	Click … to select or configure an entry. Default options include: OPCIS Asynchronous IO (OPCIOASYNC) and OPCIS Synchronous IO (OPCIOSYNC). The entry is from the TRS.CMT3 table. The Table Driven 3 field defines the type of communication between the OPCIS and the OPC server. This attribute provides the functionality of the OPC_IO_TYPE configuration file keyword at the group level. If set to OPCIOASYNC the OPCIS will use asynchronous callbacks, since asynchronous I/O is not supported by the OPCIS. If set to OPCIOSYNC the OPCIS will use synchronous IO. See OPCIS Groups for more information.	Blank
