Invalid Item SubType for Creation

Hva betyr TSM_E_INVALIDITEMSUBTYPE ?

The provided nSubType parameter for creating a child item is invalid or not compatible with the parent item's type (0x98510003). The usable subType depends on the parent tree item's category; for example, a PLC Functionblock may only be added to a PLCFOLDER item, not a DEVICE item.

• An attempt was made to create a TwinCAT item with an invalid sub-type.
• Trying to instantiate a device object with incorrect attributes.
• Incorrect configuration parameters for a specific sub-component type.
