5-2-2 FINS Commands
The CPU Unit can perform the following file memory operations when it
receives the proper FINS command. These are similar to the Programming
Device functions.
FINS Commands via Host Link
A computer connected via a Host Link System can send a FINS command
with a Host Link header and terminator.
FINS Command from Another Network PLC
Another PLC on a network can send FINS command using CMND(490).
Note A computer on an Ethernet Network can read and write file memory (Memory
Cards or EM file memory) on a CPU Unit through an Ethernet Unit. Data in
files can be exchanged if the host computer functions as an FTP client and
the CS/CJ-series PLC functions as an FTP server.
