ISPSoft User Manual Here we explain the difference between “Scan” and ‘Upload” with an example as follows. While Scan function is to scan the current configuration of modules and function card, “Upload” is to reread the CPU parameters and modules configuration stored in the CPU PLC, which may not be compatible with the actual hardware configuration under current connection. For example: Download the following module configuration to the CPU. Then remove the 16AN module and enable the “Scan” function. The result would be same as the actual configuration. Continue to enable the “Upload” function.
After operation complete, the result turns out to be same as the configuration we downloaded earlier. On-line Mode Click “On-line Mode” on HWCONFIG tool bar under the Communication tab or use shortcut key Ctrl+F4 to switch to on-line mode. To disable On-line mode, simply click “On-line Mode” on HWCONFIG tool bar again or use shortcut key Ctrl+F4. Before goes into On-line mode, the parameters of hardware configuration stored in the CPU PLC will be checked for the consistency with the module setting in module configuration area. If there’s any inconsistency, the system would request for re-downloading the configuration parameters. 3-30
