(9) If the users do not want to write the setting into the PLC for the time being, they can click OK to
apply all the setting. When the ISPSoft project is saved, the setting values are also saved.
(10) In addition to writing the setting into the PLC by clicking Set in PLC in the Retentive Range
window, the users can write the setting into the PLC when the program in the project is
downloaded. After the users click Download PLC on the toolbar, they can select the
Retentive Range checkbox in the Transfer Setup window, and click OK to download the
setting to the PLC. Please refer to section 13.1.2 for more information.
3.1.3 Connected Information
If ISPSoft is connected to the PLC normally, the system will automatically retrieve the system
parameters from the PLC after users double-click Connected Information in the project
management area. The system parameters retrieved will be organized in a hierarchical structure
under Connected Information. Users can view the information here, but they can not carry out any
setting.
