33.6
FNC295 – INITER / Initialize ER
Outline
This instruction initializes (to “HFFFF” <K-1>) extension file registers (ER) in a memory cassette (flash
memory) before executing SAVER (FNC291) instruction.
Because INITER (FNC295) instruction is not supported in FX
3UC
PLCs former than Ver.1.30, use INITR
(FNC292) instruction instead.
→
For SAVER (FNC291) instruction, refer to Section 33.2.
→
For INITR (FNC292) instruction, refer to Section 33.3.

Explanation of function and operation
1. 16-bit operation (INITER and INITERP)
“n” sectors of extension file registers in a memory cassette (flash memory) having the same device number
as
are initialized (to “HFFFF” <K-1>).
Initialization is executed in units of sector.
The table below shows the head device number in each sector:
Operand Type
Description
Data Type
Device number of extension register having a same device number of extension
file register to be initialized
It is possible to specify only the head device number in a sector of extension
registers.
16-bit binary
n
Number of sectors of extension registers and extension file registers to be
initialized
