Troubleshooting Guide
For most error messages, ther
e is a selection for “Com Troubleshooter”. This program will guide you through the
steps to solve your communication problems. Below is a quick summary:
Problem: Will not communicate
Hardware Check:
Verify the following
1. COM port number set in the HART Communicator application is the HM-BT-BAT-ER COM port number noted in
Step 5
2. Loop power supply is on
3. Loop resistance is between 250 ohms and 1Kohms
4. Loop current is within HART limits
5. If multi drop configuration, all transmitters in loop have unique addresses
6. HM-BT-BAT-ER connections are across loop resistor or across transmitter terminals (step 7)
7. Battery is charged
8. Modem power switch is on and
“Power” LED is illuminated
9. Perform the “Discovery” procedure again and
verify a connection can be made
10. If using the Linksys USBBT100, verify the Linksys Bluetooth driver is installed and not the Windows Bluetooth
driver. There is a known issue with the Linksys install and Windows XP SP2. Go to www.linksys.com and search for
“USBBT100”
for details
Software Check:
Sometimes a Windows application does not end cleanly and the communication process is left running in an
unknown state. When this happens, please restart the HART Communicator using the Windows power option
“Restart”
.
Problem:
Get the message “Error opening COMx”
Verify the following Installation
1. The Bluetooth HART Modem is charged and turned on
2. Via the Windows operating system ensure Bluetooth is enabled and turned on
3. Via the Windows Bluetooth menu ensure the Bluetooth HART Modem is listed as connected. If you have several
Bluetooth HART Modems in the same area the Windows discovery process needs to be repeated. The modems will
appear as “HART Modem (1)”, “HART Modem (2)”, etc. Where the number indicates the order in
which the modems
established a connection to your device. It may require trial and error to determine which modem is connected to
the desired HART network.
4. Note the COM Port number given to the Bluetooth HART Modem by
clicking on the “HART Modem” when i
t is
shown as “Connected”
in Bluetooth devices. This will show the services Windows has allocated to the Bluetooth
HART Modem. You should see the Serial Port number (or COM Port number) assigned to the “HART Modem”. The
service may be listed as “AMP
-
SPP”.
If your device has assigned two COM Port
numbers to “HART Modem”, the one
listed as “Outgoing Port” is the number you need to note.
5. Within DevCom2000 check the used COM port number is the same as that noted for the Bluetooth HART modem
by choosing Options
→
Basic on the DevCom2000 menu.
Problem: No data in the Communication Log
Verify
that the “HART Activity” LED indicator on the bottom of the
DevCom2000 screen is flashing red. If not, open a
menu that has dynamic data that is being refreshed like PV or AO.
