Your machines may not deliver all the data you need for proper operations assessment. Variables such as Cycle Time, Maximum Temperature, Downtime Reason, etc. may not exist, yet are essential for operations analysis.
Advanced Tags deliver an array of mathematical and logical operators enabling the generation of new data, or the aggregation of existing data into information suitable for higher level archival and analysis. Through 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, valuable for future analytics.
Advanced Tags are similar to I/O Tags. Advanced Tags enable you to create an expression, browsing from existing data tags, and combining them with math and logic operators to generate a new result. Using the OPC DA Client driver it is possible to bring data from other OPC DA Servers as well.
And, now, with the addition of Link tags, it is possible to bridge data between different protocols, between different devices using the same protocol or even between addresses on the same device. Use any tags available in TOP Server as input and output tags, reading from one input and writing that value to the specified output, with configurable trigger conditions for when a write should occur.
Proper operations analysis and assessment requires industrial control applications be able to deliver an array of data. Often times this data will require some form of calculation to be made. These calculations will help determine if operations are functioning properly and identify deficiencies which need to be addressed. The Advanced Tag Plug-in allows you to eliminate time-consuming scripting functions for analysis and bridging within your client application, saving you time and money and helping to improve decisions and efficiencies in your industrial control applications.

Pre-Defined Linking, Logic and Math Tags:
- Average Value Tags
computes the running average of a tag value
- Maximum Value Tags
show the highest value for a selected tag
- Minimum Value Tags
show the lowest value for a selected tag
- Derived Value Tags
are used to provide math and/or logic operations on one or more tag values.
- Link Tags
are used to link data between different protocols, between different devices using the same protocol or between addresses on the same device
These functions can be combined to perform complex math routines and evaluations.
- Arithmetic Operations
Add, Subtract, Multiply, Divide, Modulo (remainder)
- Functions
Absolute Value, Arc Cosine, Arc Sine, Arc Tangent, Cosine, Sine, Tangent, Power (exponential), Square Root
- Logic
And, Equal To, Greater Than, Less Than, Not True, Or etc
- Oracle Cumulative Tags
Returns the delta between the last value polled and the current value polled from a specific tag
- Complex tags - used to group multiple tags of varying data types as a single complex structure ONLY for use with the Oracle Connector Plug-in
