A.1.3
Digital communication
Model 1700/2700 transmitters support the following digital communications:
Service port
•
One service port can be used for temporary connection only
•
Address 111
•
Uses RS-485 Modbus RTU signal, 38.4 kilobaud, one stop bit, no parity
HART/Bell202
A HART/Bell202 signal can be superimposed on the primary mA output and used for interface with a
host system:
host system:
•
Frequency: 1.2 and 2.2 kHz
•
Amplitude: 0.8 mA peak-to-peak
•
1200 baud
•
Requires 250 to 600 Ohms load resistance
HART/RS485 or Modbus/RS485 (transmitters with analog outputs option board only)
One pair of terminals provides RS-485 communications:
•
Can be used for direct connection to a HART or Modbus host system
•
Accepts baud rates between 1200 baud and 38.4 kilobaud
F
OUNDATION
fieldbus or PROFIBUS-PA transmitters
One pair of terminals provides F
OUNDATION
fieldbus or PROFIBUS-PA communications:
•
Resource, transducer, and function blocks per F
OUNDATION
or PROFIBUS specification
