The configuration of process control equipment within a par-
ticular system dictates the response to the controlled process
of that system. Configuration may include such items as
cross-limits, interlocks and alarms dealing with bad quality,
and safety control equipment. Modern electronic process con-
trol equipment based on semiconductor technology is highly
reliable and can be expected to provide long trouble-free ser-
vice. However, component failures that disrupt process control
are still possible. In addition, power line induced failures, fail-
ures caused by human error, static discharge, conducted and
radiated EMI, acts of nature such as lightning strikes, and
accidents can cause disruption of process control.
