Limitations of the Setpoint attribute.


A numeric has been created and has its Setpoint attribute = true.  Its value is being calculated and set by a Plain English program.  When the controller is reloaded the numeric assumes a different value than expected.

  • CX
  • ACX
  • BCX
  • b3
  • i2


The setpoint attribute is designed to restore the point value that is stored in the ContinuumDB.  The database does not know when changes are made to the points value by a Plain English program since this occurs at the controller level and not at the database level.  


The setpoint attribute is not designed to restore last calculated value to a point on reload of a controller.
