0:06 Welcome to this Application Explainer video, part of our Instrumented Systems topic range.
0:11 In this video, we’ll cover an overview of the Instrumented Systems module.
0:15 The Instrumented Systems module is where SLM users can design their safety instrumented systems and associated independent protection layer structures.
0:26 Maintaining data in the Instrumented Systems module provides the user with a complete, accurate and up to date safety requirement specification available on demand.
0:36 The Instrumented Systems module also serves as an auditable trail that can be used for independent verification of sys data and structures.
0:45 If we come to the Instrumented Systems module and select A unit, we can see a display in the object tree of the objects that are available at the unit level.
0:53 They consist of alarms, BPCSS, cause and effect matrices, equipment, fire and gas functions, HIPS, interlocks, CIFS, and CIS’s.
1:02 These objects can be manually added to the object tree at the unit level by using the Edit Tools drop down in the Unit view template area.
1:10 So if we select Edit Tools, we can see a list of all the objects that can be added to the unit level Safety instrumented systems.
1:18 If we expand the tree is comprised of fire and gas functions, HIPS, interlocks, and safety instrumented functions.
1:28 These objects contain voting structures which are visible in the object tree.
1:32 A voting structure describes the programming logic of the SYS Sifs.
1:38 HIPS and interlocks consist of logic solvers, input groups, and output groups.
1:44 So if we expand this first SIF, we can see we have an input group.
1:52 If we expand into there, we have the input voting group, and inside here we have a list of inputs which if we drill down on an input, can also have setpoints.
2:04 We also have voting set points underneath the input voting group.
2:08 If we select any of these objects or voting groups, we can see their data entry template here on the right hand side.
2:14 If we close the input group and look at the logic solvers, we can see we have a logic solver in here.
2:20 And if we expand the output groups, we have an output voting group and inside there we have outputs.
2:28 Again by clicking on the output.
2:30 You can see the data entry template here on the right hand side.
2:33 Data entry tabs are found at the Alarm Interlock, BPCS, SIF, HIPS and SIF objects.
2:40 So if we select this SIF we can see a list of the data entry tabs at the top.
2:44 So we have an overview, we have a general tab calculations, and if we scroll to the far right, all the information from the data entry tabs are aggregated in the SLM Design SRS tab.
2:57 This tab provides an Evergreen single source of SRS data and reports.
3:02 To print out an SRS report, we select the tab, we come over to the left to the print button and select it.
3:09 We then choose our download location and click Save, and now we have a PDF report of our SRS.
3:25 It’s worth noting that objects created in the Instrumented Systems module such as alarms, BPCSS, Interlocks, sys, sys, logic, solvers, inputs, outputs, they’re all automatically mirrored in the Operate and Maintain module where the user can manage the record testing and event data.
