Information

In this example, components that can read from multiple items at once are demonstrated.

The writeItems component is given two input signals which it writes to two items on a MatrikonOPC Server (opcServer). The readItems in turn reads those same items from the server and provides the signal to the output, y.

This is a model where two items are read and written to using the same component
