System hardware, control

Both organizations update their standards from time to time, primarily because the continuing evolutions in control-system hardware provide additional possibihties for implementing control schemes.

Research users need full access to the functional elements of the spectrometer system and require the most efficient and flexible tools for MR sequence and application development. If the measurement methods delivered with the software do not adequately address the specific investigational requirements of a research team, modem NMR software is an open architecture for implementing new and more sophisticated functionality, with full direct access to all hardware controlling parameters. After evaluation, the new functionality can be developed with the help of toolbox functions that allow rapid prototyping and final builds, to enable the new sequence to be executed by non-experienced personnel and then used in routine applications. These toolboxes provide application oriented definitions and connect to standard mechanisms and routine interfaces, such as the geometry editor, configuration parameters or spectrometer adjustments. 

Then in Chaps. 7 and 8 we will look at closedloop systems. Instrumentation hardware, controller types and performance, controller tuning, and various types of control systems structures will be discussed. 

First we will look briefly at some of the control hardware that is currently used in process control systems transmitters, control valves, controllers, etc. Then we will discuss the performance of conventional controllers and present empirical tuning techniques. Finally we will talk about some important design concepts and heuristics that are useful in specifying the structure of a control system for a process. 

Separate rooms should be provided for I/O wiring panels, the process distributed control computer hardware and related systems. Motor Control Centers (MCC), UPS, and battery rooms. A minimum 1-hour fire-rated partition wall should be provided to ensure isolation of I/O and MCC areas from control rooms. 

Where practical, the distributed control system hardware areas should be provided with an independent HVAC system. 

The system is based on an XP Zymate laboratory robot controlled with a 10 slot System V controller using software version XP VI.S2. The system incorporates commerdaUy available hardware, as well as custom hardware. A schematic diagram of the system is shown in Fig. 6.11. The robotic arm and the peripheral laboratory stations that the robotic arm interacts with to perform the appHcation are positioned in a circular configuration. The GC/MS is located adjacent to the bench top, such that the injection valve is close to the sipper station. Peripheral items of hardware with which the robotic arm does not directly interact with are outside the working envelope. 

The autosampler system is controlled by an IBM computer system, as is the series of pumps for the cell and the sample wash pot. An Archer single board computer (Sherwood Data System) programmed via ASCII strings along an RS232 interface, controls the pumps and the autosampler, setting up a stable representative sample which is then measured by using the standard Solomat software and hardware. 

The history of the FDA is a story of continuously stepping back. Is the product free of contaminants Then step back and consider the process of production. Is the product well organized and safe Examine next the hardware and software systems that control that manufacturing process. Every time one level of concern has achieved industr3rwide predominance it is possible to apply the energies used to achieve that awareness and compliance to yet another previous step. The process is, in effect, continuous quality improvement in action.

Two different software applications have been developed for this complex reaction system (1) Hardware control and automation this application enables one to set and control the pressure, liquids and gas flow and pressure, as well as the position of the mechanical parts of the system. It also allows one to program the variation of the different reaction conditions (64 variables in each reaction step) (2) Analysis and reaction monitoring this application enables the on-line monitoring of the GC analysis results and reporting, which facilitates the off-line data analysis and leads to nohuman data manipulations in the transfer to the genetic algorithm application.

The integration of the computer system (hardware, software, and instrumentation) must be confirmed in readiness for the subsequent OQ activity. Some practitioners have referred to this as the testing of static attributes of the computer system. The importance of completing the IQ before commencing the OQ can be illustrated by a recent incident in which a pharmaceutical company had over 35% of the instrumentation for a multiproduct plant but did not have available calibration certificates. There were various reasons for this, but none were recorded. Some instruments were no longer used, some had extended recalibration periods, and some had been undergoing calibration for several weeks. The net effect was that the computer system under quahfication was clearly not in a controlled state suitable for the OQ, and in consequence, it was not ready for use. 

Hardware, software, and data (local and remote) should be protected against loss, corruption, and unauthorized access. Physical security is required to prevent unauthorized physical access by internal and external personnel to computer system hardware. Logical security is required to prevent unauthorized access to software applications and data. The network and application software should provide access control.

The reader is referred to the NCCLS standard AUT03-A, which is described in the following and in particular to the Functional Control Model (Section 4.2), which describes the relationships between the LIS, LAS, and various devices. In this model, and throughout the series of NCCLS automation standards, the term LAS represents the computer system that controls the automation system, not the actual automation hardware. Most often, it is the LAS that has the requisite process control software to support automation. The functional control model, which is depicted in Figure 11-19, supports analytical instruments that may be physically attached to the automation system and analyzers that may not be attached but are still interfaced to the LIS. The model does not give dominance to either the LIS or the LAS, but rather allows for essential information flows in either direction to make the most efficient use of the strengths of each system. 

Fundamentally, EGA systems require powerful software control and data analysis systems, which, in addition to overall hardware control and displaying and analyzing output data, may also store reference libraries of MS or FTIR spectra to assist identification of the gaseous products of a thermal decomposition. However, EGA represents the most comprehensive group of thermoanalytical systems available for the characterization of the thermal behavior of materials.
