How a Lifecycle Automation Audit Is Performed
The audit follows a layered engineering approach: Learn How a Lifecycle Automation Audit Is Performed with Sis Automations Services
Thank you for reading this post, don't forget to subscribe!1. Asset Lifecycle Mapping
Each automation component is classified as:
Active
Mature
Obsolete
High-risk (unsupported or failure-prone)
This includes PLC CPUs, I/O cards, HMIs, servers, drives, and network devices.
2. Reliability & Performance Analysis
Key indicators are evaluated:
PLC scan time margin
CPU and memory utilization
Network latency and packet loss
HMI/SCADA response time
Alarm rates and nuisance alarms
These metrics identify systems operating near failure thresholds.
3. Environmental & Electrical Stress Review
Common hidden failure causes are analyzed:
Panel temperature rise
Power supply loading
Harmonics and voltage imbalance
Grounding and noise susceptibility
4. Risk-Based Prioritization
Findings are ranked using:
Failure impact
Downtime cost
Safety exposure
Replacement lead time
This allows upgrades to be planned instead of rushed.
Why This Audit Saves Money
Facilities that implement lifecycle audits typically:
Reduce unplanned downtime
Extend usable system life
Avoid emergency retrofit premiums
Improve safety compliance
Gain budget predictability
