Instruction List
33.5 RWER / Rewrite to ER
Outline
This instruction writes the current values of an arbitrary number of extension registers (R) in the PLC's built-in
RAM to extension file registers (ER) in a memory cassette (flash memory or EEPROM) or to the extension file
registers (ER) in the PLC's built-in EEPROM.
Because RWER instruction is not provided in the FX
3UC PLC earlier than Ver. 1.30, use SAVER instruction
instead.
