A control strategy can represent any control code, such as process control, I/O, data flow, and visualization for a control entity. A control strategy can be a 2- state device, a PID loop, a sequencing block:  Controller code  IO data  Controller data  HMI Server data  HMI Client data  HMI DL data  Batch data  Historian data  Using the control strategy model, we are able to estimate these system parameters:  HMI server tags on scan (alarm tags, display tags, data log tags, event detector tags, and derived tags)  Controller memory usage  Controller execution time 18

All rights reserved. #PSUG System Performance Criteria in “Operational” Terms 1Display Call up A HMI Display “Paint Time” is the time it takes to call up a new screen (not cached) and must be operational in less than 2 seconds 2Display Data Update A change in a active value within any controller is displayed on a graphic screen on the OWS (HMI client) in less than 1 second. 3Steady State Alarms The System must support a Steady State alarm condition, consisting of twenty new alarms being generated every second, with the difference between the time an alarm is triggered and its timestamp not exceeding one (1) second (cannot miss any alarm) 4Alarm Burst The System must support an Alarm Burst condition, consisting of one thousand (1000) new alarms generated all at once, with the difference between the time any alarm is triggered and its alarm timestamp not exceeding three (3) seconds (cannot miss any alarms) 5System Recovery Within five (5) minutes after a failed System Element is restored, the system should recover and perform as it did before the system element failure 6Data Logging The system will be capable of continuously data logging a minimum of 200 independent points once a second 7Paint Time for Datalog Trend A datalog trend display will present 12 hours of historical data of any data logged point on the OWS within 30 seconds of the operators display request. 8Operator Control The operator will be able to interact with the process by changing tag values in the controller within 2 seconds. 9Control Loop Update Time The system will be capable of supporting 125 Complex Regulatory Control Loops (cascaded) within a 250ms periodic task. This time is from instrument to actuator. 10Batch Server: Operator Action Time An operator initiated Batch command will be responded to by the PAC with 1 second. 11Batch Server: Server Action Time A batch server initiated Batch command will be responded to by to the PAC with 1 second. 12Batch Server: Controller Action Time A batch Event in the Controller will provide the operator with feedback in 1 second.
