8.2.1 MachineToolIdentificationType ToC Previous Next index

The MachineToolIdentificationType of the Machine Tools information model holds static data which shall uniquely identify a machine tool among a pool of the machine tool operating entity. It is a subtype of the MachineIdentificationType defined in OPC 40001-1, so it inherits all InstanceDeclarations specified there.

The MachineToolIdentificationType is formally defined in Table 10.

SoftwareIdentification contains a list of instances of the SoftwareIdentificationType (see Table 12). This list contains the machine tool’s software identification information. It allows to add multiple software items, e.g. one for each of PLC, NC and HMI.

SoftwareRevision inherited from the MachineIdentificationType shall contain an overall software patch level of the machine tool. Individual software revision numbers may be given using SoftwareIdentification.

For the DeviceClass inherited from the MachineIdentificationType, the values in Table 11 shall be used. The most appropriate value, based on the main machine tool technology shall be chosen. Detailed definitions can be found at http://www.rotebuch.de.
