8.3 Communication settings
8.3.1 Settings for the HART interface (only for devices
with the optional HART interface)
This group contains the setting functions for the HART interface.
Setting the polling address
The polling address configures the device for analog operation
(4 to 20 mA) or multidrop operation. Analog operation
(4 to 20 mA) is activated by setting the polling address to 0.
For multidrop operation the polling address must be configured
to a value between 1 and 15, which will result in the analog
interface being deactivated and set to a constant current of
approx. 1 mA. To allow the control unit to request the Unique
Identifier (unique HART address) with HART command #0,
all the devices on a line must be configured with different
polling addresses. It is advisable to choose a sequence
starting with 1 and incrementing continuously.
This setting corresponds to HART command #6 (Write Polling
Address).
1. Select Settings > Communication > HART interface >
Polling address and confirm.
2. Select the address line for the entry and confirm in order to
switch to the Change mode.
3. Set the polling address and confirm.
4. Select Confirm and confirm.
