When adding an ISPSoft project, the system uses the project name as the PLC CPU name by default and appears after the model type in the Project section which can be redefined from here. By using PLC label name for device identification, especially during networking applications or connecting, users can avoid operating mistakes through checking the PLC label name; several devices are connected to one network, users can check whether a device connected to the computer is the device they expect by checking the device name.
To prevent errors, if users want to download/upload the program, the system will remind the users to check the name of the CPU module and the name attached to the model in the project management area, when the name of the CPU module is different from the name attached to the model in the project management area. 3-161
