I am integrating a large Invensys (Schneider Electric) EMS to a new system. My point of integration is the JACE, also known as the Universal Network Controller. The UNC allows you to assign an instance number using the Block editor in the Enterprise Server or Work Place Pro. This is a tedious task. There must be a way to assign the instance numbers in groups or by using find and replace. I cannot find the instance numbers in the XML file. It would be nice if the shadow object could be assigned an instance number. Has anyone found a way to speed up this process?
