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.
