A distributed control system (DCS) normally uses input and output modules which contain eight, sixteen, or more inputs or outputs. Failure of the module will simultaneously disable a large number of control loops. Attention to the assignment of input/output points to the modules makes the plant more tolerant of a failure of an input or output module (CCPS, 1993a). For a more detailed discussion of process control systems, see the process control part of Section 4.4, and Sections 6.4 and 6.5. 

In the proportional control mode, the final control element is throttled to various positions that are dependent on the process system conditions. For example, a proportional controller provides a linear stepless output that can position a valve at intermediate positions, as well as "full open" or "full shut." The controller operates within a band that is between the 0% output point and the 100% output point and where the output of the controller is proportional to the input signal. 

The curve Da(Gz 1) is limiting, because it corresponds to process parameters, which provide the minimum necessary level of adhesive strength. The area below this curve (at a definite mold temperature Tm) corresponds to the Da and Gzn Numbers, for which the degree of conversion is less than the critical level these parameters do not provide the maximum output. Points above this curve, represent inadmissible process parameters, which do not provide the required level of polymer-metal adhesive strength. 

Flow accuracy across a range of backpressures and solvent compositions can be evaluated by collecting and weighing timed aliquots of solvent. Pressure readings are plotted on a strip-chart recorder from a transducer signal output point. The recorded values should be within the manufacturer s specifications and as consistent and close to the programmed values as possible. 

GMP critical control input/output points typically in order of 5 to 10% of total input/output points. This has led many pharmaceutical manufacturers to consider the use of validated independent monitoring systems for the GMP critical control points and hence alleviate validation of the control system to a Good Engineering Practice (GEP) activity based on qualihcation." Independent monitoring systems range in complexity ... 

The main task of DDAPLUS is to compute the state vector u (and the sensitivity matrix W if requested) at the next output point. The status of the solution upon return to the calling program is described by the parameter Idid, whose possible values are explained below. 

To control access to the cabinet, a solenoid lock and thumbwheel can be installed on the door of the field cabinet and wired to input/output points on the controller. The access code is specified by the system programmer and should be a pair of combinations that will be easy for the maintenance workers to remember. Upon entry of the correct code or a process instability, the solenoid will be de-energized to permit entry. This arrangement makes it unnecessary for production personnel to know the access code, and the unlock algorithm detailed in the figure uses a 10-s timer to frustrate clever operators. 

EQPS calculation. Given sufficient output points from EQ6, the isotopic fractionation calculations provide more detailed information than present analyses of sulfur isotopic compositions for several reasons. Firstly, EQPS calculations are sufficiently fast that small step sizes are not a problem, especially when coupled to graphic output routines. Secondly, calculated EQ6 pathways are smooth and continuous between discontinuities, which are forced by EQ6 to be part of the output set of data points. This results in a typical computed 6 " S uncertainty of less than 0.05 per mil, which are sensitive to zoning and varying solution isotopic composition during precipitation. In contrast, sulfur isotopic analyses are limited by sample size requirements and heterogeneous mixtures of phases. 

Critical and potentially critical faults to common components (such as faults to CPU/RAM/ROM) typically inhibit nearly the entire processing of data and are therefore more far reaching than a fault of a single output point. Failure modes that carry a high failure probability have to be detected with more confidence. Furthermore, the detectability of failure modes should be taken into account.

Numerical integration methods discussed so far provide information about the solution of the ODE at certain discrete points. The location of these points is determined by the step size control. Often however, the numerical solution is needed at other points, so-called output points. This situation occurs due to... 

In the first case the location of the output points is often not known explicitly and is determined iteratively by solving an implicit relation. This will be the topic of Ch. 6. 

The Control and Estimation Tools Manager menu should look like Fig. 9.8. As ean be seen, the input point is the feed flow and the output point the concentration from the mass balance. On this display, now select Linearize Model , this will produce the Bode diagram for the linearized reactor model as shown in Fig. 9.9.

Figure 2 shows a generic body J that has an input point located at the joint between itself and its father and one or more output points ry, etc., located at the joints between itself and its children. 

If the double-sided complex transform is performed, the number of operations increases. For each value of Vj, we now perform N multiplications for Sa k)cosInVjkh, and N multiplications are required for Sa k)sia2nVjkh. Then TV — 1 additions must be made for the cosine transform and TV — 1 for the sine transform, so a total of approximately 4N operations must be made for each wavenumber. If the full bandwidth of the spectmm is to be examined at the same resolution as the single-sided spectmm, twice as many data points must be taken so the number of operations is increased to 8TV. The number of output points is the same as for the single-sided case, so that 4TV operations are required. This number does not include the time required for the cosine, sine, square, and square root calculations required for each value of Vj.
