When configuring a SmartConnector, the custom assembly cannot be seen in the Add Processor Configuration tab
EcoStruxure Building Operation
This is usually because the dll’s for the custom processor have been downloaded from an internet based source. Some files need to be "unblocked" after download in order to avoid security warnings from tools like Visual Studio about potentially unsafe content.
Otherwise, all the required dll’s for the solution may not be available in the service installation directory (normally “C:\Program Files (x86)\Schneider Electric\SmartConnector”). This information can be seen in the SmartConnector log file. SmartConnector will log an error when going to the point of adding a new processor if it can’t find a reference. It will point to the assembly which is missing.
To "unblock" a file, right-click it in Windows Explorer, choose Properties from the context menu, click the Unblock button in the lower right-hand corner of the resulting dialog, and hit OK or Apply:
Important: ZIP files should be "unblocked" before their contents are extracted.
