A major oil refinery is employing the Analog I/O Modules with HART Protocol into their extensive control system. The modules provide digital communication with plant instrumentation. This ability also allows devices to be periodically read and configured, including commissioning.  

The Analog I/O Modules with HART Protocol offer:

• better resolution of the process variable
• more process information from the multivariable devices
• significant savings in time for instrumentation setup
• the elimination of incorrect configurations; and 
• remote instrumentation configuration 
  through the program code.

Spectrum Controls' modules were immediately compatible with not just the PLC, but with the HART devices. For systems with devices in proximity to the control system, a lower cost was achieved due to the lower cost of the HART instruments versus the newer more costly buss instruments.

The 1756sc-IF8H Analog Input Module with HART Protocol was successfully  incorporated into their well testing and steam generator process control. The process uses the following instruments:

• Rosemount pressure, temperature and
  3095FT multivariable
• Micro-Motion coriolis flow
• Drexelbrook capacitance level; and
• Magnetrol radar level.
