LM (former EMS): misleading information when user manually enters wrong min/max switching times.

LM (former EMS): misleading information when user manually enters wrong min/max switching times.

Summary

Issue in Load Management when then user edits the switch-on/off time and makes min value bigger max value:

  • no warning message during compilation of project. In the Runtime wrong configured component is treated like switchable and comes along with switch planning process, but will be never switched.
  • misleading information in the LOG (DiagViewer): "minimum switch on time ConsumerABC does not end in actual tariff interval; not scheduled"
When the component gets wrong min/max times not from Editor but from linked variables the information in LOG is correct - the component is listed as not switchable ("restrictions not plausible").     Issue affects all kinds of LM power components (consumers and generators).  

Description

Issue in Load Management when then user edits the switch-on/off time and makes min value bigger max value:
  • no warning message during compilation of project. In the Runtime wrong configured component is treated like switchable and comes along with switch planning process, but will be never switched.
  • misleading information in the LOG (DiagViewer): "minimum switch on time ConsumerABC does not end in actual tariff interval; not scheduled"
When the component gets wrong min/max times not from Editor but from linked variables the information in LOG is correct - the component is listed as not switchable ("restrictions not plausible").     Issue affects all kinds of LM power components (consumers and generators).  

Solution

The compiler is enhanced now with the plausibility check of configured min/max switch times (max > min, if max != 0 ). In the Editor the configuration mistake causes error message in output window. Then in the Runtime the Load Management for affected supply area cannot be started.

When using wrong settings via linked variables, the component gets internal switching state "Restrictions are not reasonable" and the component (consumer/generator) is not switchable.
