Applies To:
  • CitectSCADA  7.00
Summary:

By using the WinNewAt function with parameter
"128 - Open a unique window.
This mode prevents this window from being opened more than once".

However, in v7.0, it is still possible to open the popup windows several times.  

Solution:

The function call must contain the cluster name.
The optional parameter "cluster name" must be declared, else we get the bad bahaviour.

Citect has confirmed this to be a problem in CitectSCADA version 7.00. This issue will be fixed in a future release of the product.

In the case of CSV_MM_WinNewAt there is no optional Cluster definition. In this case the page name can be prefixed with the Cluster name: "CLUSTER.PAGE"
