Downloading the firmware

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 Remote Indicator supports only one type of
download class as per FOUNDATION Fieldbus specifications. RMA803 REMOTE INDICATOR
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 ID
•
Retains only its System Management VFD in its VFD_LIST
•
Retains its Node Address and PD Tag
•
Retains its management VCR to provide access to the SMIB.
ATTENTION
Note that the Node Address and PD Tag does not retain, when the firmware
is upgraded from one version to the other.

Recommendations

If firmware upgrade is required for a large number of RMA803 REMOTE INDICATOR devices,
the following are the guidelines,
1. Backup Diagnostics must be done only during the firmware update. The diagnostics will
initialize to zero if this is not done during the firmware update.
2. Only one device firmware download is allowed in a given H1 Link process:
Firmware download to multiple devices must happen one after another in the same link.
However, parallel downloads can be performed to devices on different H1 links.
3. Download firmware to one device type at a time in a H1 link:
This reduces the chance for unknown interactions between devices to cause link issues or
download failures.
4. Reduce usage of DTM through tools like FDM in the H1 link:
