Description:Unique identifier/address/number for devices of the same DeviceType within a local network. Several peripheral devices of the same DeviceType can be connected to a machine. In most applications, the machine must map the connected peripheral devices to internal logical devices and zones in a fixed configuration (e.g. hot runner systems according to the wiring or temperature control devices according to the tubing).The mapping shall be stable after reconnecting the devices and is therefore not possible via IP addresses, which can be assigned dynamically via DHCP. DeviceMappingNumber sets the mapping order of peripheral devices of the same type on the local network and is therefore of type UInt32.
