Creating a Formula

About this task

Building a formula with the Server-to-Server Collector is the same as building a formula in a calculation tag. For additional instructions, refer to the following sections in Calculation Collector:
  • Creating a calculation Formulation

  • General Guidelines for Designing a calculation formula

  • Verifying the syntax of a calculation formula

You can expect thousands of tags per second to be processed, depending on your calculation formula. However, the destination server has a limited number of incoming events per second, which is shared by all collectors.

For polled collection, for instance, you can expect to perform hundreds of calculations per second. Polled calculations, using calculated data functions, are slower than unsolicited calculations using the CurrentValue() function.
