Smart Field Communicator

The handheld Smart Field Communicator (SFC) is a battery-powered device which establishes secure two-way communications between Honeywell Smart Transmitters and the user over the existing signal lines.

The SFC is extremely useful for simplifying maintenance by providing access to field devices without a trip to the field. When the SFC is connected to the transmitter signal lines at an accessible location anywhere from the control room to the transmitter, the operator can send and receive data from the transmitter’s microprocessor.

The SFC is in an impact-resistant housing and comes with test leads, a weather-proof carrying case, a Ni-Cd rechargeable battery pack and a battery charger.

Features

The SFC has many functions:

  • Select the communications mode - The transmitter can be configured to transmit its output in either an analogue (4-20 mA) mode or in the digital communications (DE) mode.
  • Configure - Operating parameters such as LRV, URV, damping, failsafe mode and input actuation type for the STT may be programmed into the transmitter using the SFC.
  • Diagnose - Access the Smart Transmitter’s self-diagnostic capabilities to troubleshoot suspected operation or communication problems.
  • Check calibration - The SFC provides a simplified procedure for checking calibration of Smart Transmitters, thus maintaining excellent transmitter accuracy and significantly reduced maintenance requirements. The accuracy of the SFC’s digital readout of the transmitter’s output may be certified allowing the STS103 to be used as part of calibration schemes following ISO 9000 procedures. Re-ranging of the transmitter is also possible using the STS103.
  • Display - All configuration parameters as well as other data such as PROM/serial number, tag name, sensor temperature (ST), hi/lo PV (STT) and scratch pad memory can be read on the two-line LCD display. The STS103 also displays measured process variables (pressure, differential pressure, flow rate) in selectable engineering units.
  • Checkout - By configuring the transmitter for the output mode you can command the smart transmitter to transmit a precise signal, selectable from 0 to 100 percent full scale to assist in verifying loop operation, loop calibration or troubleshooting.
