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