Fields

Polling Address HART can communicate with up to 15 devices on a single pair of

wires. These devices are distinguished by their polling address

which is a number from 0 to 15. If there is a device at polling

address 0, it must be the only device on the loop. There may be up

to 15 devices with non-zero polling addresses on the loop (subject

to power and intrinsic safety constraints). Devices which operate

4-20 mA are generally required to have polling address 0, however

with split range valve positioners, several4-20 mA devices may be

wired in series. These devices should be set up with non-zero poll-

ing addresses.

Switches The SVI can measure the status of too contact switches (open or

closed). See the operating manual for connection information.
