1. FINS commands for file memory operations can be sent from host comput-
ers connected via a Host Link, another PLC connected to a network (using
CMND(490)), or the local PLC's program (using CMND(490)). (For CS-se-
ries CS1 CPU Units that are pre-EV1, file memory operations cannot be
executed using CMND(490) in the same CPU Unit for which the file mem-
ory operations are being performed.
2. Other Operations: Format file memory, read file data, write file data,
change file name, read file memory data, delete file, copy file, create sub-
directory, and change file name.
3. Data files with the TXT or CSV formats can be read and written only with
the FREAD(700) and FWRIT(701) instructions. They cannot be read and
written with a Programming Device.
