1-14 SIL PolicySIL ComplianceDistribution and WeightThe programmable controller may conservatively be assumed tocontribute 10% of the reliability burden. (See Figure 1.3.) A SIL 2system may need to incorporate multiple inputs for critical sensorsand input devices, as well as dual outputs connected in series to dualactuators dependent on SIL assessments for the safety related system.(See Figure 1.3)Figure 1.3 ControlLogix Systems or Loop+V10% of the PFD40% ofthe PFDSensorInputModulePowerSupplyControllerDiag.OutputModuleActuator50% of the PFDSensorInputModule43383+V10% of the PFD40% ofthe PFDSensorInputModulePowerSupplyControllerStandardOutputModuleActuator50% of the PFDSensorInputModuleMonitoringInputModule43384Publication 1756-RM001B-EN-P - October 2003
SIL Policy 1-15Agency CertificationsUser documentation shipped with ControlLogix products typically listthe agency certifications for which the products are approved. If aproduct has achieved agency certification, it is marked as such on theproduct labeling. Product certifications are listed in the product’sspecifications table, as shown in the example below.Certification UL UL Listed Industrial Control EquipmentCSAFMCECSA Certified Process Control Equipment for Class I, Division2 Group A,B,C,D Hazardous LocationsFM Approved Equipment for use in Class I Division 2 GroupA,B,C,D Hazardous LocationsEuropean Union 89/336/EEC EMC Directive, compliant with:EN 50081-2; Industrial EmissionsC-TickAustralian Radio Communications Act, compliant with:AS/NZS 2064; Industrial EmissionsResponse TimesThe response time of the system is defined as the amount of time ittakes for a change in an input condition to be recognized andprocessed by the controller’s ladder logic program, and then to initiatethe appropriate output signal to an actuator. The system response timeis the sum of the following:• input hardware delays• input filtering• I/O and communication module RPI settings• controller program scan times• output module propagation delaysEach of the times listed above is variably dependent on factors such asthe type of I/O module and instructions used in the ladder program.For examples of how to perform these calculations, see Appendix A,Response Times in ControlLogix.For more information on the available instructions and for a fulldescription of logic operation and execution, see the followingpublications:• Logix5000 Controllers General Instruction Set Reference Manual,publication 1756-RM003.• ControlLogix System User Manual, publication 1756-UM001.These publications are available from Rockwell Automation.Publication 1756-RM001B-EN-P - October 2003
