1.1 Classification
Three classes of devices are relevant for the wizard:
1. Functional devices, not (yet) assigned to a physical device.
· These devices have an associated function.
· These devices are not aggregated below a device.
Upon loading in a selection list they are shown in the left area of the dialog Merge Device Wizard.
2. Free physical devices, devices to which no functional device has been assigned.
· These devices do not have an associated function.
· These devices are aggregated below a device.
Upon loading in a selection list they are shown in the right area of the dialog Merge Device Wizard. The related attributes are represented in black.
3. Occupied, physical devices, devices to which a functional device has already been assigned.
· These devices have an associated function.
· These devices are aggregated below a device.
Upon loading in a selection list they are shown in the right area of the dialog Merge Device Wizard. The related attributes are represented in blue.
The wizard merges functional and free physical devices which have the same device type and separates occupied physical devices.
In addition, further requirements have to be fulfilled when functional and free physical inputs and outputs are merged:
1. The I/O type of the functional channel has to correspond to the I/O type of the automation device or the I/O board.
2. For outputs and inputs, the value of the attribute Symbolic Address will be taken into account:
· Outputs and inputs with filled attribute Symbolic Address are always listed among the functional devices.
· If you activate in the dialog Options on the tab Attributes the checkboxes Device Option – In Use for the rows “Output” and "Input”, then, when reloading the device data, the list of functional devices comprises outputs and inputs with empty attribute Symbolic Address, too. After selecting automation devices and I/O boards, you may assign these devices to their channels in the dialog area on the right.
