Chapter 6 Symbol Variables Specific models with the latest hardware versions support three new initialization processes, Stop Run initializing retentive symbols, Stop Run initializing non-retentive symbols and Initializing retentive symbols. Please refer to section 3.1.5 and download the configured initialization setting to the PLC device before downloading the project. ISPSoft would detect automatically whether the connected device supports the new initialization processes. If yes, the option “Symbol Initial Value(Active when STOP RUN)” would not able to be unselected as shown below.
After the initial values download is complete, go to PLC (P) > Initial value setting (I) > Initial retentive symbols must be checked (R), then confirm on the initialization action, as well as the normal connection between ISPSoft and the CPU 6-35 Model Types Hardware Ver.
