Hi,

When you have compiled the CFC as block type, it means in the project or library (depends where you execute it), a new FB is created with the parameters you have set.

Next you can create a CFC chart and drag and drop the newly created FB in the chart. You have to make sure that you have configured inputs and outputs in the Chart I/O with the correct s7 attributes. For example, you can create an input with attribute: s7_m_c = true. This means the input is send to the OS and can be viewed on the OS.

When you have inserted the FB, the CFC editor creates an instance of it. Each block you insert is an instance and you can monitor them individually in test mode.
