3.38 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
The operation history function consists of the following functions.
Operation history of device data writing and writing of files by operation of the CPU module itself or the execution of
functions (writing device data or file internally) are not saved.
Note 3.26
The operation history function can be used only with the High-speed Universal model QCPU and Universal model
Process CPU. When using the operation history function, check the versions of the CPU module and the programming
tool used. ( Page 465, Appendix 2)
