5.1 Outline of write operation
Programs are written to the memory inside the PLC when the online mode is selected, and to the inbuilt HPP
RAM when the offline mode is selected.
When the online mode is selected, if a memory cassette (except the EPROM) is attached to the PLC,
programs are written to the memory cassette. (When using the EEPROM, set the write-protect switch to OFF.)
Programs can only be written while the PLC is in STOP mode.
New programs can be written, and existing programs can be overwritten for modification.
When writing a new program, input instructions from the step No. 0 in turn. When overwriting an existing
program for modification, put the cursor on a position to be modified, then input an instruction.
