HSCI components have their own firmware, which must match the currently
installed NC software version. Every time the control is started, the NC
software checks the firmware versions of the individual HSCI components.
After a software update, during initial operation or after replacing a hardware
component, a firmware update may be required.
Note
The control must not be switched off during a firmware update!
If the NC software detects that a firmware update is necessary, you will be
prompted by a dialog box to start the firmware update. The firmware updates
are included in the NC software update package. Please read the notes on
firmware updates under "Firmware update on HSCI devices" on page 147.
When the firmware versions of all HSCI participants have been updated, the
control boots until the "Power interrupted" message appears.
During startup, a control in an HSCI system expects the complete
configuration of the HSCI system in the form of an IOC file. The IOconfig
software for PCs is used to configure the system, the PLC input/output
systems (PL 6xxx, UEC 11x, MB machine operating panel with a connected
HR handwheel ) and the PROFIBUS components.
With IOconfig, the components of an HSCI/PROFIBUS system are specified
in a project and their arrangement is described. On the basis of this data,
IOconfig generates the IOC file (*.IOC) that contains all relevant configuration
data for the HSCI system. Then you transfer the IOC file to the control. With
the MP_iocProject machine parameter (103402) you enter the path and name
of the project file (e.g. %OEM%\IOC\Structur.ioc). When the control is next
booted, the file is read in and evaluated by the control.
Note
All information required for using the IOconfig PC software and configuring
HSCI and PROFIBUS components is contained in the IOconfig Technical
Information, which is available for registered customers from the
HEIDENHAIN FileBase on the Internet.
