If the IM component is provided, it must contain the data of the representative submodule for the device in accordance with the I&M0FilterDataDevice block (See [PN TAD] – Identification & Maintenance).

The Assets and IM objects are optional. If the interface is used with the OPC UA facet model, the asset data can be part of another facet (See chapter 6 “PROFINET OPC UA Information Model” and Figure 16 – “Facet” modelling approach for I4.0 System Modelling).

The <Assets> objects are only assets which are directly related to this device. Assets related to the modules or submodules are components of these objects.

The server may provide diagnosis data with the Diagnosis variable or by sending PnDiagnosisAlarmType events. The diagnosis data at the device object includes the diagnosis information of the whole device including the one of all real modules and real submodules. An OPC UA Server might provide instances of the PnDiagnosisAlarmType as objects under the Alarms object.

6.3.1.3.1.1 ShowLocation Method

This optional method shall trigger a perceivable signal which allows the identification of the physical device represented by the device object the method is invoked on. This is usually accomplished with a blinking LED.

The method has no parameters (no [in] and no [out] parameters) and no return value.

The BrowseName of a device object instance shall be the content of the NameOfStation variable of the first interface sub module. If the NameOfStation variable is not set, the content of the MAC Address variable of the first interface sub module shall be used. The MAC address string should use the canonical format (separated with -, e.g. AC-FD-CE-EC-03-80).

If the GSDDescription property is provided, it must contain the InfoText with Device Id from the GSD (see mapping table below).
