It is important that signal conditioning modules include sufficient filtering at the output of the module to eliminate this noise source. Output switch speed is another aspect of signal conditioning, one that's too often overlooked in many data acquisition applications. For example, in some applications many signal conditioning modules share the same data acquisition channel. Each module, in turn, is turned on, and the channel is measured. Faster turn-on means that more channels can be acquired within a given time period.

The system has to be expandable, preferably with only incremental costs, as this will allow one to start small. This is particularly important in the absence of a precise definition of future requirements, as is the case with most CIM implementations. A modularly designed system may also be desirable, as most systems are implemented in modules over considerable periods of time. A modular system is likely to be cost-effective in the long run without the initial purchase of excessive capacity. The system has to conform to some form of standards-international, national, or industry-wide-so that it can be easily interfaced with equipment from multiple vendors.

It's important to note that FMSs reduce or eliminate setup times, which in turn leads to greatly reduced batch sizes and greatly increased communications traffic in the factory. If not taken into consideration, this fact may render the traffic load estimation null and void. • Applications profile-Compiled by determining the importance of the applications to the company, their revenue impact, the consequence of a system breakdown, transmission error, and response time fluctuations. The applications profile provides information for evaluating the relative importance of such design criteria as cost, performance, and reliability, and also for estimating the expected savings due to improved productivity.
