Operation History Function

This function saves the operation information of device data writing and writing of files from outside the CPU module
such as the programming tool, GOT, SLMP/MC protocol, and FTP into the CPU module as an operation history file,
and displays it in the programming tool. Even if a problem occurs in the system due to incorrect operations, the history
of operations to files and devices helps users to detect the incorrect operation and to investigate the cause of the
problem.Note 3.26
