Yokogawa Standalone MW100 - Manual (Page 212)

4-20 IM MW100-01E
4.7 Updating the System
You can upgrade the MW100 main unit firmware to the latest version. When you upgrade
the version, you can use the upgraded firmware on the MW100.
Note that to add new functions by upgrading the style, you need to purchase the style
upgrade kit.
CAUTION
• If you update the firmware, all settings such as the IP address and range
settings are reset to factory default values. Saving the current settings to the CF
card before updating the firmware makes it easy to reconfigure the MW100 after
updating the firmware.
• The IP address, subnet mask, default gateway, host name, domain name, date,
and time are not saved to the setup file. Take a note of the IP address, subnet
mask, default gateway, host name, and domain name.
• Be sure to update both the firmware and Web software. Otherwise, the operation
may become unstable.
• Depending on the firmware style (release number), it may also be necessary to
upgrade the MW100 Viewer software. For details, visit our Web site or contact
your nearest Yokogawa dealer.
