18 Transmitter Configuration and Use: Series 1000 and 2000 Transmitters
Connecting with ProLink II Software continued
Figure 3-6 Model 1700/2700 IS: Resistance and voltage requirements for HART/Bell202 connections
6. Start ProLink II software. From the Connection menu, click on
Connect to Device.
7. Set
Protocol to HART Bell 202. Baud rate, Stop bits, and Parity are automatically set to the
values required by HART protocol.
8. Set the
Address/Tag value to the HART polling address configured for the transmitter. The
default HART polling address is 0. See Section 8.15 for information on the HART polling
address.
9. Set the
COM Port value to the PC COM port assigned to this connection.
10. Set
Master as appropriate:
• If another host such as a DCS is on the network, set
Master to Secondary.
• If no other host is on the network, set
Master to Primary.
Note: The 275 HART Communicator or 375 Field Communicator is not a host.
11. Click the
Connect button. ProLink will attempt to make the connection.
12. If an error message appears:
a. You may be using incorrect connection parameters.
- Ensure you are using the correct COM port.
- If you are unsure of the transmitter’s address, use the
Poll button in the Connect
window to return a list of all devices on the network.
b. Check all the wiring between the PC and the transmitter.
c. Increase or decrease resistance.
