Chapter 5 AADvance Functional Safety SystemImplementationReplacing/installing processor modulesProcessor modules can be replaced or installed on-line without affecting the controlleroperation provided at least one is fitted and is fully operational. However, processorsmust be installed one at a time and allowed to educate before the next processor isinstalled.When a processor module is installed and the locking screw set to the lock position,the module will automatically start to educate from the existing operating processor.The Healthy indicator flashes GREEN during the educating process and goes steadyGREEN when educated. The Run indicator stays RED during the education processthen goes steady AMBER when educated. After the Reset button is pressed the Runindicator goes steady GREEN and the newly installed processor module becomesoperational. If the Run indicator stays AMBER or reverts back to RED then educationprocess has failed and either the module is faulty or the application is invalid.Processor Module Access PortThe front panel of the 9110 Processor Module has a concealed PS/2 style connector onthe front panel behind a plastic cover. This connector is for ICS Triplex use only and isused for factory settings during manufacturing. The plastic cover should only beremoved to replace the processor battery.I/O Module Safety FunctionsThis section describes the adjustable safety parameters that you can set.Module Safety Related ParametersThe Workbench provides you with the capability to adjust two safety relatedparameters for an I/O module: Process safety time Shutdown action of a digital output module channelI/O Module Process Safety TimeThis option allows the system integrator to configure the process safety time (PST) foran I/O module, independently from the system value set through the processormodule. If no independent value is set for the module it will adopt, by default, the toplevel value of PST set for the processor module. When an input module exceeds thePST, that is the controller does not receive an update from the application within thePST then the I/O module is set to a fail safe state and returns a safe values to thecontroller.Digital output module process safety timeDocument number 553630 Issue 7: February 2010 5-19
