About SFC Communications

The portable, battery-powered SFC serves as the common communication interface device for Honeywell’s family of Smartline Transmitters. It communicates with a transmitter through serial digital signals over the 4 to 20 milliampere line used to power the transmitter. A request/response format is the basis for the communication operation. The transmitter’s microprocessor receives a communication signal from the SFC, identifies the request, and sends a response message.

Figure 5 shows a simplified view of the communication interface provided by an SFC.

ATTENTION

Because of the advanced capabilities built-in to the SMV 3000, we do not recommend that you use the SFC to configure the SMV transmitter. Some of the SMV’s advance functions are not supported by the SFC. Although you can use the SFC to perform certain operations, such as calibrate or re- range the transmitter, read transmitter status and diagnose faults.

Using the SFC with the SMV 3000

If you use the SFC to communicate with the SMV, you can adjust transmitter values, or diagnose potential problems from a remote location such as the control room. You can use the SFC to:

Monitor:

Read the input pressure, process temperature, or

 

 

secondary variable to the transmitter in engineering

 

 

units.

Display:

Retrieve and display data from the transmitter or SFC

 

 

memory.
