33.6 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 instruction.
Because INITER instruction is not provided in the FX
3UC PLC earlier than Ver. 1.30, use INITR instruction
instead.
→ For SAVER instruction, refer to Section 33.2.
→ For INITR instruction, refer to Section 33.3.
