The remaining area of FP-ROM (flash memory) for screen data storage can be
sued as a data backup area of the PLC memory, internal memory or memory
card. A maximum of 16k words can be used as a data backup area.
* In this case, the available capacity for screen data is reduced by 128 kbytes.
•

1. Each FP-ROM allows 100,000 write operations.
(Each time the FROM_WR command is executed, it is counted as one
regardless of how many words are included.) Consequently, reduce the
number of write operations, such as reading backup data at power-up and
writing data for backup before turning the power off.
2. Do not execute the FROM_WR or FROM_RD command in each cycle
using CYCLE macro.
3. Writing to FP-ROM takes three to five seconds.
