A.1.5 Modbus
®
(output option code M)
Output
The RS-485 Modbus version communicates by Modbus
RTU, Modbus ASCII, and Levelmaster protocols.
8 data bits, 1 start bit, 1 stop bit, and software selectable
parity.
Baud Rate: 1200, 2400, 4800, 9600 (default), and 19200
bits/s.
Address Range: 1 to 255 (default device address is 246).
HART communication is used for configuration via the
HART terminals or tunneling via the RS-485.
External power supply
The input voltage U
i
for Modbus is 8-30 Vdc (max. rating).
For Explosion-proof/Flameproof installations the
Rosemount 5300 Series Transmitters have a built-in barrier;
no external barrier needed.
