33.1 FNC290 – LOADR / Load From ER
Outline
This instruction reads the current values of extension file registers (ER) stored in a memory cassette (flash
memory), and transfers them to extension registers (R) stored in the PLC's built-in RAM.

• Reading and transfer are executed in units of device. Up to 32768 devices can be read and transferred.
• Different from SAVER (FNC291), INITR (FNC292) and LOGR (FNC293) instructions, it is not necessary to
execute this instruction in units of sector.
• If "n" is set to "0", it is handled as "32768" when the instruction is executed.
