The 4500 is set to address zero (0) at the factory, which allows operation in the standard point-to-point manner with a 4–20 mA output signal. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 15. This change deactivates the 4–20 mA analog output, sending it to 4 mA. It also disables the failure mode alarm signal, which is controlled by the upscale/downscale switch position. Failure signals in multidropped transmitters are communicated through HART messages.

To activate multidrop communication, the transmitter poll address must be assigned a number from 1 to 15, and each transmitter in a multidropped loop must have a unique poll address.

HART Communicator

1.From the HOME screen, enter the fast key sequence for “Changing a Transmitter Address.”

AMS

Right click on the device and select “Configuration Properties” from the menu.

1.In the “HART” tab, in “ID” box, enter poll address located in the “Poll addr” box, click Apply.

2.An “Apply Parameter Modification” screen appears, enter desired information and click OK.

3.After carefully reading the warning provided, select OK.

HART Communicator

To communicate with a multidropped transmitter, configure the HART Communicator to poll for a non-zero address.

1.From the HOME screen, enter the fast key sequence for “Communicating with a Multidropped Transmitter.”

2.On the polling menu, scroll down and select “Digital Poll.” In this mode, the HART Communicator automatically polls for devices at addresses 0-15 upon start up.

AMS

Click on the HART modem icon and select “Scan All Devices.”

Polling a multidropped loop determines the model, address, and number of transmitters on the given loop.
