Appendix 2-5 Disabling the EWF Function

Display the command prompt screen, then input the following command to disable
the EWF function. The next time that the Unit is normally restarted or shut down,
the data that was emulated on the main memory will be reflected on the Memory
Card. After the Unit is normally restarted, the data on the Memory Card will be
directly written.
Command: ewfmgr c: - commitanddisable
Execution example

Appendix 2-6 Precautions

• When the EWF function is enabled, since the data written to the Memory Card
is emulated on the main memory, the system memory space will be reduced
and operation may become unstable when a large amount of data is written. To
prevent this problem, it is recommended that large amounts of data be written
to a memory media other than the Memory Card.
• The writing lifetime per sector of the Memory Card on this Unit is 100,000 cycles.
In order to increase the reliability of the Memory Card, it is recommended that
the Unit be used with the EWF function enabled.
• In the Industrial PC, the OS and RAS Utility store the event logs in the D: drive.
Consequently, the EWF function must be disabled with respect to the D: drive in
order to save the event logs even after the Industrial PC is restarted.
