Product Overview

The Advanced Tags plug-in for KEPServerEX offers a convenient, cost effective, and straightforward way to generate new data and aggregate existing data into information suitable for high-level archive and analysis. Using Advanced Tags, users can measure the duration of operations, totalize events, perform averages over a group of sensors, set trigger conditions for data acquisition, and combine machine conditions to generate an overall machine state. These capabilities are extremely valuable for future analytics.

Using Tag Linking, Logic, and Math Functions for Operations Analysis

Proper operations analysis requires that industrial control applications deliver an array of data. This data often needs some form of calculation to identify deficiencies and help determine whether operations are functioning properly. The Advanced Tags plug-in for KEPServerEX will help improve decision-making and efficiency in your industrial control applications. Get started now with easy-to-use, pre-defined tags.

Pre-Defined Linking, Logic and Math Tags

  • Average Tag - Calculates the average value of a tag over a defined time.
  • Complex Tag - Groups multiple tags of varying data types as a single complex item or structure.
  • Link Tag - Links data between different protocols.
  • Maximum Tag - Reads and persists a tag's maximum value over a defined time.
  • Minimum Tag - Reads and persists a tag's minimum value over a defined time.
  • Oracle Cumulative Tag - Determines the difference between the current and previous values. This tag is defined by Oracle and is available to all OPC Client applications.

Derived Tags

Derived tags use basic scripting and standard Logic and Math functions to provide calculations exceeding those of pre-defined tags. They have the ability to control the frequency and conditions with which an expression will be evaluated, and also enable users to incorporate more complex equations into their applications. To aid implementation, an expression validation tool is included along with expression examples (located in the Advanced Tags manual).

Benefits of Advanced Tags

  1. Cost

    Use with existing micro, nano, and less capable PLCs. There is no need to purchase expensive PLCs or PACS.

  2. Time

    Consistent methodology across all hardware and software platforms. A single application configures Linking, Logic and Math functions.

  3. Performance

    Reduce network traffic and improve bandwidth by reducing communications between the server and multiple client applications.

  4. Reliability

    Ensure data consistency across all clients with a single data access point.

  5. Knowledge

    No special PLC or HMI programming skills are required.

  6. Data Sources

    Collect and manipulate data from a variety of applications and devices.

  7. Project Modification

    Easily modify and configure new and existing Linking, Logic and Math functions with a straightforward user interface.

For an inexpensive operational analysis tool, consider using the Advanced Tags plug-in for KEPServerEX along with the DataLogger plug-in and any ODBC-supported database. KEPServerEX also supports DDE connectivity, thus allowing the powers of Microsoft Excel and Advanced Tags to combine.

Release Notes

2015-06-23

EX5 - 5.18.662.0

  • Added support for bulk enable/disable of tags in the user interface.
  • Added the ability to undo a CSV import at the project level.
  • Quality is now set to bad with a configuration error when one or more of the tags the Advanced Tag references is invalid.
  • Quality is now set to bad with an out of service message when the user disables the referenced tag or one of its parent groups
  • Added support for reading Advanced Tags even when they are inactive. This allows an OPC client to add the Advanced Tag as inactive, perform a read, and get the most recent value.
  • Added a new quality keyword for Derived Tags. This allows derived expressions to use the tag quality as well as the tag value.
  • Enhanced the Link Tag to support a Link While True trigger mode. While in this mode, all changes to the input tag are written to the output tag at the given link rate.

2015-02-24

EX5 - 5.17.495.0

  • Removed repeated error messages when the plug-in fails to add a tag reference.
  • Fixed a memory leak that was caused by the plug-in failing to load a 'Complete' tag reference.

2014-11-18

EX5 - 5.16.728.0

  • Fixed an issue that was introduced in the 5.16.722.0 release where the initial value of a Derived Tag could be corrupted after a CSV import.

2014-10-21

- 5.16.722.0

  • Fixed an issue with Derived Tags where a device read from a client caused the Derived Tag's expression to execute.

2014-07-22

EX5 - 5.15.585.0

  • For the On Input Value Change (Ignore Initial Update) trigger, BAD quality is no longer considered a change of value and is ignored. This was done to ensure that the initial update is ignored whether it is good or bad quality.
  • Enhanced Derived Tags to allow string comparison using the equals (==) operator.
  • Fixed an issue where advanced tag trigger expressions that used string tags were not working properly.

2014-02-18

EX5 - 5.14.491.0

  • Enhanced Link Tags to have the new trigger mode option On Input Value Change (Ignore Initial Update). This mode is identical to the existing On Input Value Change option, except that the initial update does not cause the Link Tag to write to the output. This is useful when the initial value in the Input Tag is not required or meaningful.
  • Fixed a Link Tag issue where the output would not get updated if the input read returned too rapidly, as seen with internal or simulated tags.
  • Updated the XML schema to allow for tag descriptions up to 255 characters. Corrected the size of the address field to be 1024 characters.

A plug-in is an advanced option that extends the capabilities of the KEPServerEX communications platform. It increases the usefulness of data by transforming it beyond raw data in a device register.

Plug-ins may be licensed individually or in suites. Additional plug-ins can be licensed on demand as connectivity needs evolve.
