Firmware Updates
Firmware version 1.3 provides the following enhancements:
•
Two new register groups, 46XXX and 47XXX, provide for positive and negative power/energy
measurements, respectively. These registers allow PowerScout 3 use for generating or drawing
power such as solar or wind applications.
•
New register 44604 provides a measurement sequence number. This register increments each
time a measurement is completed. The register is set to zero every minute.
•
Delta loads may now be measured using only two CTs. (Previous firmware versions required
three CTs to measure a delta load.)
•
The enhanced I/O operation allows direct I/O control/status. The control setting is stored for
initializing during a power cycle.
•
Multiple register reading is enhanced using a single modbus command, 03, Read Holding
Registers. The registers are not changed until the command is complete.
Downloading and Installing Firmware
1.
Download the zip file containing the firmware. Extract the zip file to a folder on the computer.
2.
Connect the computer to the PowerScout. Refer to Section III,
Installing the ViewPoint
Software and Communicating with the PowerScout
for additional information.
If connectivity fails with the 9600 baud rate, refer to the
Troubleshooting
section at the end of
this appendix.
3.
Select the baud rate for loading the firmware to the PowerScout.
A baud rate of 9600 downloads the firmware to the PowerScout in approximately six minutes.
A faster baud rate can be selected to reduce the time by approximately 2.5 minutes.
Change the baud rate using the
Communications
tab. Select the desired baud rate. The baud
rate is synchronized between ViewPoint and the PowerScout by clicking the
Connect
button.
