
Now add an GNVL object in the V3 project from the 23.gvl (option "import from file")
which serves to read variable trans23 from the 2.3 PLC.
Abb. 32 GNVL in V3 project
Now, if both the V23 project as well as the V3 application are running within the
network, the V3 application can read variable trans23 from project 23.pro.
3.12 Code Generation and Online Change
Code Generation, Compile Information
Machine code will not be generated until the application project gets downloaded to
the target device (PLC, simulation target). At each download the compile information,
containing the code and a reference ID of the loaded application, will be stored in the
project directory in a file "..ID>.compileinfo". The compile info will be deleted when the Clean resp.
Clean all command is performed.
Regard that no code generation is done when the project is compiled by the 'build'
commands. The build process is done to check the project for syntactical errors. Those
will be dumped in the Messages window (message category 'Build').
Online Change
WARNING!
Online Change modifies the running application program and does not effect a
restart process.
Make sure that the new application code nevertheless will effect the desired
behaviour of the system.
Depending on the controlled system, damages to machines and parts could result,
or even health and life of persons could be endangered.
