256 Power disruption during firmware upgrade
Section 6: Meter operation Reference, Installation, and Operations Manual
June 2013 3-9000-743 Rev S
Normal meter operation continues while the new program is being downloaded and stored in
FLASH memory. A new program generally does not affect the meter configuration and archive
logs.
Once the program download is complete, the Mark III meter restarts in order to run the new
program components. Daniel MeterLink issues a message that it must disconnect from the
meter due to the meter re-start. Once the meter is re-started, re-connect to the meter with
Daniel MeterLink.
6.8.1 Power disruption during firmware upgrade
If the program failed to download to a Daniel Mark III Ultrasonic Gas Flow Meter during a
firmware upgrade, Daniel MeterLink can no longer connect to the meter or a message
“Attempt
FTP-only connection….”
is displayed when trying to connect.
It is possible for the meter to lose its programming if the meter power fails during a firmware
upgrade process. If this occurs, follow the special procedure known as a Backup Upgrade
described below, to make a connection to the meter and re-attempt the download process.
1. In Daniel MeterLink, use the
File|Program Settings menu and select Allow FTP-only
connection
.
Figure 6-6 Program settings dialog FTP-only connection
2. Click the
OK button to close Program Settings dialog.
3. For Serial Port Connections: If you are connecting to the meter over a serial port, make
sure you are connected to Port A or Port B on the meter Field Connection Board. Note:
You can not program the meter from Port C if the meter is not currently running a
program.
