2. Update the EAZ project
The only way to ensure that all HDD files specified in the IOC file are evaluated
and used for generating the HSCI components in an IOC project is exporting
and importing an IOC file. These steps are required to be able to detect new
components, diagnostic information and parameters in new HDD files.
The essential steps are creating an IOC file and re-importing this IOC file.
These steps ensure that all diagnostic information is updated and all new
parameterization possibilities become visible.
If the message Missing HDD files is displayed during import, press CONTINUE
to continue the process. Then the slave is inserted, but it will not have any
diagnostic or parametric properties.
This can happen if the names of HDD files were changed and the IOC file still
contains the previous file names. A new IOconfig version with current HDD
files will usually not find these old files. If it finds them nevertheless, then
move the old HDD files and make sure that you do not use them
anymore.
Something similar can occur if the name of an HDD file is correct, but the
name of the slave contained in it was changed and the IOC file still contains
the old name of the slave. The error message Missing HDD files will then not
be displayed, but the diagnostic and parametric properties of the slave will be
missing.
In such cases, the slave in question must be deleted and reinserted from the
correct HDD file. The new functions provided by IOconfig 2.2.02 for this
purpose can be used to transfer the terminal names during the Delete/Paste
actions.
3. Check the machine operating panels and keyboard units
If the Override module is shown for an MB/TE slave, then the respective slave
must be deleted and reinserted from the correct HDD file. The new functions
provided by IOconfig 2.2.02 for this purpose can be used to transfer the
terminal names during the Delete/Paste actions.
