3. GENERAL INFORMATION
3.1 Hardware Description
The FGM 160 Field Computer, illustrated in Figure 1, is designed as a distributed system. The
FGM 160 consists of five or six modules, the Digital Signal Processing (DSP) module, the
Analog Front End (AFE) module, the Pressure & Temperature (P&T) module, Input/Output
(I/O) module, Intrinsic Safe Barrier (IS Barrier) module, Surge Protection module and the Local
Display. A distributed system gives several advantages. This design will be more flexible with
respect to future expansions and modifications, as the total processing load for the system can
be divided in several modules. Thus, the danger of overloading a single CPU unit is reduced.
