Operational ConstraintsInstallation TopologyA compact installation, with instruments concentrated near the control room, willfacilitate a centralized architecture that supports the integration of the masters withthe PLC. An example of this is shown below.HMI or SCADAPLCMaster 1Master 2I/O and sensorsI/O and sensorsBy contrast, an installation extended with distant or non-concentrated instrumentsrequires a distributed architecture, with higher costs for wiring. Because the distancebetween the instruments and their masters is limited, distribution by group isnecessary. The diagram below provides an example of such an architecture where,masters and PLC are connected on the same Ethernet network.HMI or SCADAPLCMaster 1 Master 2I/O and sensorsI/O and sensors12
EnvironmentInstrumentation management is dependent upon the environmental constraints andregulatory standards for applications in a dangerous environment.The specific EU directives are as follows:• The directive “users” 99/92 specifies the constraints for sites owners regarding thesafety of the workers and environmental protection.• The directive “manufacturers” 94/9 specifies the constraints for materialmanufacturers.These directives are more commonly known under the name of ATEX (ATmosphereEXplosive)For more details, see the website: http://ec.europa.eu/enterprise/atex/indexinfor.htmThe European directives identify several classification criteria:• The type of industry• The nature of the atmospheric risk (gas or dust)• The risk level in each specified danger zoneThe following table summarizes this classification:Area ClassificationZone CriteriaGasesDustsZone 0 Zone 20Zone 1 Zone 21Zone 2 Zone 22xxxPresent continuously or for longperiods(>1000hrs per annum)Likely to occur in normal operationoccasionally (>10hrs, >1000hrs perannum)Unlikely to occur in normal operation,If it does will only be for short perioda(>10hrs per annum)13
