ATTENTION
In the SLG 700 FF level transmitter, only communication board firmware can
be upgraded using the class 3 download. Display and sensor boards'
firmware upgrade is not possible through FF link.

About firmware download feature

The download class indicates how the device operation is affected by the download process. There are
three types of download classes (1, 2 & 3). The transmitter supports only one type of download class
as per FOUNDATION Fieldbus specifications. SLG 700 device FF variant supports download type
Class 3 only. A class-3 firmware download is performed, irrespective of whether the device is ON
/OFF process.

Class 3

When class 3 download is performed the device prepares for the download and goes out of the link as
the memory of the device is re-written with the new firmware. After the restart of the device, the
device comes back to the link automatically. However, the device retains the following credentials:

Retains its original device identification

Retains only its System Management VFD in its VFD_LIST

Retains its Node Address and PD Tag (only when the same firmware version is reloaded)

Retains its management VCR to provide access to the SMIB.
