Issue:
The PowerSCADA Expert equipment tree, when used to filter alarms, behaves erratically and performs very slowly, particularly in the web client or when the filter form is used. Sometimes it will resolve itself but sometimes cicode will run out of threads and be unable to continue displaying the page correctly.
Product Line:
PowerSCADA Expert 8.0 SR1
PowerSCADA Expert 8.1
PowerSCADA Expert 8.2
Environment:
PowerSCADA Runtime HMI alarm page with equipment tree
Cause:
In the design of the alarm filtering, the Equipment Tree filtering and filters created by the popup form do not inter operate. Because of this, when the form criteria is applied, or when reset filter is clicked, cicode attempts to uncheck all of the equipment tree nodes to remove that filter. When the alarm tree is large enough or system performance constraints are tight enough (e.g. web client), this will cause the tree nodes to flash seemingly randomly as checked and unchecked until it reaches a steady state with all nodes unchecked or cicode runs out of threads causing the HMI to stop working.
Resolution:
A workaround has been created to modify the cicode in PLS_Include. If this is needed for a customer site, contact L4 support. The changes will be incorporated into future patches.
