Searching for multiple coils will start, and the results will be displayed in the Check for Multiple
Coils Pane.

played results do not match the data in the linked Machine Controller.
When you check for multiple coils and use a project link connection, first always read the data to
the project file from the Controller.
If the Enable to Multiple Coil Check Check Box is selected in the compile options, a search for
multiple coils will be performed during compilation and the results will be displayed as warnings in
the Output Pane.
