Macro
To rewrite the station number table on the V series screen, use macro commands [FROM_WR] and [RESTART].
FROM_WR
FROM_WR F0 F1
Function: Writing to FROM
As many words as specified for F1 from the device memory address set for F0 is written in the FP-ROM.

Data range
Notes
- The maximum possible number of write operations to the FP-ROM is 100,000 times. This is not related to the number
of words that are written.
- Do not include the FROM_WR command in a cycle macro or an event timer macro.
- Writing to FP-ROM takes a longer time.
- When the station number table has been rewritten using the [FROM_WR] command, be sure to execute the [RESTART]
command.
- When the station number table is used, it is not possible to set [ Use Internal Flash ROM as Back-up Area] on the
[General Settings] tab window that is displayed by selecting [System Setting] [Unit Setting] [General Settings]. Be
sure to leave this box unchecked.
