January 2012 3.18 Configuring the PLC Inputs/Outputs with IOconfig 239
HEIDENHAIN provides device files (HDD files) for all HSCI components with
the technical characteristics of these components. These HDD files are of crit-
ical importance for the configuration of the HSCI system. You should therefore
make sure that you always use the latest version of IOconfig and the HDD files
for the configuration.
When configuring a project, the IOconfig program takes the description of the
HSCI components from the HDD file and transfers it to the configuration file
(IOC file).
For more information about using IOconfig, please refer to the program’s
on-line help.
Updating the HSCI
configuration
To update the HSCI configurations, proceed as follows:
Install the IOconfig version 2.2.02 or a later IOconfig version. In the HEIDEN-
HAIN FileBase, you will find the current version of the IOconfig software for
PCs for downloading. With IOconfig version 2.2.02, however, changes to the
HDD files are not transferred automatically.
If new HDD files exist on the PC, IOconfig 2.x does not update these files
automatically until these files:
are copied into the directory in which IOconfig searches for HDD files (to be
defined in Extras/Options and Project/Settings), and
are read in with the HDD import function or imported via an IOC import of
GSD/HDD files.
HDD files cannot be imported in any other way, e.g. when EAZ files are
loaded. Any existing new HDD files will therefore be ignored.
Do the following steps manually in order to be able to use all available features
of new HSCI components:
1. Transfer the HDD files
Check where the standard directory and the project directory for HDD files are
located. The two directories should usually be identical:
Extras -> Options: Standard directory for HDD library: xxxxxxx
Project -> Project Settings: Directory of HDD library: xxxxxxx
Move or delete all HDD files being used.
Then copy all current HDD files from IOconfig (e.g. from C:\Programs\HEIDEN-
HAIN\IOconfig\HDD ) to the standard directory or the project directory of the
HDD library.
HEIDENHAIN recommends updating all IOC files and EAZ projects with the
IOconfig version 2.2.02. This is the only way to ensure that you can use all
of the features provided by the new HSCI components.
