33.6
FNC295 – INITER / Initialize ER
Outline
This instruction initializes extension file registers (ER) to “HFFFF” (<K-1>) in a memory cassette (flash memory) before
executing the SAVER (FNC291) instruction.
Because the INITER (FNC295) instruction is not supported in FX
executing the SAVER (FNC291) instruction.
Because the INITER (FNC295) instruction is not supported in FX
3UC
PLC earlier 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 (ER) in a memory cassette (flash memory) with the same device number as
are initialized to “HFFFF” (<K-1>).
Initialization is executed in sectors.
The table below shows the head device number in each sector:
