#70 - SCADA Ignition Template binding with property value

On the previous post  it was shown how to create a template and bind using two different methods: Expression binding to concatenate a text with a dynamic index and Indirect Binding to bind a tag via its path. In both cases the dynamic parameter passed was the motorIndex (int) which was created into the Custom Properties.

In this post a third method for dynamic binding, called Property, is described. This method can be used, for instance, when there's not a well structured tag path or as an alternative way to connect to the OPC tags from an UDT.
