Connection of transmitters in multidrop mode:
®
The HART
communicator or a PC modem can be connected accross AB or
BC.
The outputs of max. 15 transmitters can be connected in parallel for a digital
®
HART
communication on 2-wires.
Before it is connected, each transmitter must be configured with a unique number
from 1 to 15. If 2 transmitters are configured with the same number, both will
be excluded. The transmitters must be programmed for multidrop mode (with a
fixed output signal of 4 mA). Maximum current in the loop is therefore 60 mA.
The communication is either by means of a HART
modem.
The PReset PC configuration software can configure the individual transmitter
for multidrop mode and provide it with a unique polling address.
