4.3 UIP executable representation
The implementation of the UIP depends on the type of user interface elements that can be embedded into the user interface hosting environment of the FDI Client. UIP shall be implemented as a .NET System.Windows.Forms class UserControl or a Windows Presentation Foundation (WPF) System.Windows.Controls class UserControl.
UIP executables and their required libraries shall have strong names. The signing of a strong- named Assembly can be done using a self-generated key.
NOTE The identity of strong-named Assemblies consists of a name, version, culture, public key token and digital signature.
UIP executables and their required libraries shall be shipped with file containing the public key in order to enable Assembly verification.
4.4 UIP executable compatibility rules
The compatibility rules for different versions of the UIP component are specified in
IEC 62769-4.
The compilation target platform for the UIP shall be “anyCPU”. If this is not feasible, the UIP shall be shipped in two variants. One UIP variant shall be compiled for target platform “x86”. The second UIP variant shall be compiled for target platform “x64”. The compilation platform target shall be described in the catalog.xml file, which is defined in IEC 62769-4. This catalog.xml file contains an xml element “Cpulnformation” that describes the User Interface Plug-in variant. The allowed values that shall be used in the xml element “Cpu Information” are “anyCPU”, “x86” or “x64”.
4.5 Allowed .NET Common Language Run-time versions
4.5.1 General
Specific CLR (Common Language Run-time) versions are released for the execution of software components built with specific .NET Framework versions. The .NET CLR version 4.0 is used to execute software components built with .NET Framework 4.0. .NET Components are built for one CLR version only but can be capable to run also under a newer CLR version.
FDI Clients can be built based on CLR version 4.0 or future versions. An FDI Client has to realize the following situations when starting a UIP.
• When the UIP to be started was built for the same run-time, the UIP can be started by the FDI Client as usual.
• When the UIP to be started was built with another CLR version and is not compiled for the current running CLR version, the FDI Client shall start the UIP in a surrogate process with the adequate CLR version. (More details are described in 4.5.2.)
Taking this behavior in account, a UIP shall be developed for CLR version 4.0 or any future
version. If the CLR versions do not match, the UIP shall be started in a separate process. The
UIP will then not be displayed as an integrated module within the EDI Client. It is up to the
FDI Client to realize the surrogate process.
4.5.2 CLR compatibility strategy
In the future, FDI Clients and UIPs will be permitted to be built on different incompatible versions of the CLR.
If an FDI Client detects that a UIP requires a CLR that is not compatible with the FDI Client, the FDI Client can use a proxy class that enables interaction with the UIP built using a different version of the CLR.IEC 62769-6 pdf download.
