Operational Qualification Protocol for PLC System
Meta Description: This document outlines the Operational Qualification (OQ) protocol for the PLC System used in manufacturing automation, ensuring compliance with URS Annex11 and 21CFR11.
Tags: Equipment Validation, PLC System, Operational Qualification, Manufacturing Automation
Objective
The objective of this Operational Qualification (OQ) is to verify that the PLC System operates according to predefined specifications and meets regulatory requirements, ensuring the integrity of manufacturing processes.
Scope
This protocol applies to the PLC System utilized in the production area for controlling manufacturing equipment, impacting product quality directly.
Responsibilities
The Validation Team is responsible for executing this protocol, documenting results, and ensuring compliance with relevant regulatory standards.
Prerequisites
- Completion of Installation Qualification (IQ)
- Availability of all necessary documentation, including User Requirement Specification (URS)
- Training of personnel on the PLC System
Equipment Description
The PLC System is a computerized control system designed to automate manufacturing processes. It includes functionality for logic execution, alarms, audit trail, and access control, ensuring critical parameters are monitored and controlled effectively.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| OQ-01 | Verify logic execution | Logic executes without errors | Execution logs |
| OQ-02 | Check alarm functionality | All alarms trigger as expected | Alarm logs |
| OQ-03 | Audit trail verification | Audit trail is complete and accurate | Audit trail report |
| OQ-04 | Access control testing | Access is restricted to authorized personnel | Access logs |
Detailed Test Cases
Test Case OQ-01: Verify Logic Execution
Procedure: Execute predefined logic sequences and verify that outputs match expected results.
Acceptance Criteria: Logic executes without errors.
Evidence: Execution logs to be reviewed and signed off.
Test Case OQ-02: Check Alarm Functionality
Procedure: Simulate conditions that trigger alarms and verify that alarms are activated.
Acceptance Criteria: All alarms trigger as expected.
Evidence: Alarm logs to be reviewed and signed off.
Test Case OQ-03: Audit Trail Verification
Procedure: Review the audit trail for completeness and accuracy against expected changes.
Acceptance Criteria: Audit trail is complete and accurate.
Evidence: Audit trail report to be reviewed and signed off.
Test Case OQ-04: Access Control Testing
Procedure: Test access levels for different user roles to ensure compliance with access control policies.
Acceptance Criteria: Access is restricted to authorized personnel.
Evidence: Access logs to be reviewed and signed off.
Deviations
