Connection Of Transmitters In Multidrop Mode; Appendix; Transmetteur 2-Fils Avec Protocole Hart - PR electronics 6335 Mode D'emploi

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 conected 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.
