Limitations of the Setpoint attribute.

Issue

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.

Environment

  • All controller
  • CX
  • ACX
  • BCX
  • b3
  • i2

Cause

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.  

Resolution

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

 

Note: For a possible workaround to this involving Plain English programming see LL#12598
