The control also boots without the IOC file or the entry "IOCCFG =" in the
OEM.SYS. The control then automatically detects all components connected
to the HSCI chain and the current configuration—without the PLC input/output
systems, however. Press the Accept button in the dialog box to confirm the
detected configuration and continue start-up of the control. However, further
configuration of the control is not possible. In the Programming and Editing
mode of operation, you can start BUS DIAGNOSIS after pressing the MOD
key and the DIAGNOSIS soft key. The control will display the structure of the
detected HSCI system. If required, you can use this information for the
configuration with IOconfig.
HEIDENHAIN recommends updating all IOC files and EAZ projects with the
IOconfig version 2.2.02. This is the only way to make sure that you can use
all of the features provided by the new HSCI components, see page 291.
