The dates the program and parameters were created can be confirmed by
checking the contents of A090 to A097.
Note The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units do not support
this function.

For CS/CJ-series CPU Units Ver. 2.0 or later, protection can be set to prevent
writing to and otherwise controlling CPU Units by using FINS commands via
networks (i.e., connections other than direct serial connections). This includes
writing from applications using FinsGateway as well as from the CX-Program-
mer, CX-Protocol, and CX-Process. Reading will still be possible in this case.
The following operations will be prohibited if write-protection is set: Download-
ing the user program, PLC Setup, I/O memory, or other data; changing the
operating mode; online editing; and any other write or control operations.
Even if write-protection is set, specific nodes can be set as exception to
enable executing write/control operations from them.
Protected against being written
by FINS commands sent from
nodes on networks, e.g., cannot
be written from computer #1,
