Operation

5.2.3 Data Hold During Power Failure

The FP7 CPU unit backs up most data into ROM (non-volatile memory).
 Data saved in ROM (non-volatile memory)
• Project data (programs, configuration data, comments)
• Hold type data in the operation memory
• System monitors, system records data (e.g. lifetime data, error records)
 Data held by the built-in capacitor and the backup battery
• Calendar timer
KEY POINTS

Calendar timer values can continue operation for about one week by the
built-in capacitor, even if no battery is used.

In order to charge the built-in capacitor, supply power to the CPU unit for at
least 30 minutes.

5.2.4 Online Editing

The FP7 CPU unit can be edited online. Usable operations vary by mode.
 PROG. mode
• While editing a program, the program inside the RAM is rewritten by PG converting a given
network inside the program block that is being edited.
• Rewritten data in the RAM is incorporated into the ROM1.
• Comments and configuration data can also be rewritten.
 RUN mode
• While editing a program, the program is written into the RAM by PG converting a given
network inside the program block that is being edited.
• Rewritten data in the RAM is incorporated into the ROM1.
• Configuration data cannot be rewritten.
• Comments can be rewritten.
• It is not possible to download the entire project.
• It is possible to download the Program Block (PB).
After a program is rewritten in the RUN mode, operation stops for a time length proportionate
to the size of the relevant PB.
