C h a p t e r 8 H a r d wa r e C o n f i g u r a t i o n8 - 6 28.4.5 I/O ScanUsers can configure modules in the way mentioned above. If users have gotten related hardware, they caninstall the hardware, click I/O Scan in HWCONFIG, and scan the actual hardware configuration throughcommunication. The time of configuring the modules will be saved. Users have to make sure that ISPSoft hasconnected to the CPU module normally before they carry out the operation. Please refer to section 2.4 inISPSoft User Manual for more information about communication setting.Users can click I/O Scan on the Option menu, or on the toolbar to carry out the operation. The contentswhich will be scanned include the module models, the hardware configuration, and the firmware versions of themodules, but do not include the parameters in the modules and the parameters in the CPU module. After I/OScan is clicked, the original hardware configuration and the parameter setting will be cleared. However, theparameters in the CPU module will not be affected.After the scan is complete, the actual hardware configuration will be displayed in the system configuration area,the system will assign input/output devices to the modules, the parameters in the modules are assigned thedefault values, and the firmware versions set in HWCONFIG will be the actual firmware versions of themodules. If the firmware version of a module which is scanned is higher than the firmware version of themodule in the MDS document, the highest version which can be selected will be displayed in the FirmwareVersion drop-down list cell for the module, and the actual firmware version of the module will be displayed inthe Comment cell for the module.*. Please refer to section 8.3.1 for more information about MDS documents and firmware versions of modules.The difference between I/O Scan and Upload can be illustrated with the following example. If I/O Scan isclicked, the hardware configuration will be scanned, and the parameters in the modules will not be scanned. IfUpload is clicked, the hardware configuration in the CPU module will be read. The hardware configurationuploaded to HWCONFIG may be different from the actual hardware configuration.
