January 2012 2.7 Software 147
During start-up of the control, the nominal configuration of the IOC file is
compared with the actual configuration. If there is a difference, you will be
informed of it in a dialog box. Press the Accept button to confirm the new
configuration and continue start-up of the control.
In addition to the configuration, the serial numbers of the individual HSCI
components are also saved. During start-up they are compared with those of
the detected hardware. Any difference must be checked and accepted by the
user. (See "Monitoring hardware changes" on page 149.)
The control also starts up without the IOC file or entry in the MP_iocProject
(103402) parameter. 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 mode you can start the BUS DIAGNOSIS by pressing the MOD
key and the DIAGNOSIS soft keys. The control will display the structure of the
detected HSCI system. If required, you can use this information for the
configuration with IOconfig.

During a software update or after installing a service pack, an update of the
internal firmware of HSCI components may be required.
In this case, the control displays the following error message after start-up:
Acknowledge the error message by pressing the DELETE ALL soft key.
