Use the following list to eliminate possible remote communications issues (in any order):
Verify that the symbol flashes in the A8 display position, see Figure 12-1: XSeriesG5
annunciators. This indicates that the port is actively running Totalflow Remote Protocol.
Each flash identifies the listen cycle time.
If the symbol is not flashing:
Set the port Listen Cycle to zero. The symbol should display continuously.
• Select Totalflow Remote Protocol in the configuration of the port, see section 8.7.1:
Configure COM1.
• Increase the cutoff voltage value specified in Station Setup > Remote Comm Cutoff
Voltage. This helps determine if COMM1 is deactivated due to a drop in the voltage to the
device. The default is 11.9 Vdc. Use voltage values based on the power mode used. Click
Help in the Station Setup screen for more details.
Verify that these are correct:
• The communication port wiring on the flow computer
• The communication port wiring on the radio
• All communication cables are intact and undamaged
Verify that the antenna is properly installed:
• Wiring to the radio is correct
• Frequency range is correct
• Directional antenna is pointed toward the base radio (±6°)
• Vanes are mounted vertically and are perpendicular to the ground
Verify that the base radio (host device, typically running WinCCU) is working at other
locations, using the same frequencies as the remote radio.
Verify the configuration of the host communication application (typically WinCCU):
• The Station ID and the Device ID match the host settings.
• No other device is using the same Station ID or Device ID.
• The baud rate, stop bits, security code, and listen cycle time agree between the host
(WinCCU) device and flow computer.
• The host (WinCCU) is using packet protocol.
For troubleshooting other communication equipment, including modems, cellular equipment, or
telephone line, contact the ABB Totalflow main office, listed under Contact us and select technical
support from the menu options.
