Nabız
Clear situations instead of alarm floods.
- Related alarm groups and likely root cause
- Early warning from alarm trends
- Alarm load against EEMUA 191
EVERY DECISION. BETTER PRODUCTION.
The plant's digital engineer: an AI layer that only reads DCS and SCADA data and runs offline.
Setup and security
LIVE IN FOUR STEPS. DATA NEVER LEAVES
- 01
Discovery
We review the control system, alarm load and documents together.
- 02
Installation
Installed on an on-site server, read-only to the DCS; no shutdown needed.
- 03
Learning
Past alarms and plant documents are processed.
- 04
In use
Results are measured in fault resolution time and unplanned downtime.
Frequently asked questions
MERIDYEN IN DETAIL
What is Meridyen?
Meridyen is Cervoi’s predictive maintenance (PdM) and fault management application for process plants. It analyses DCS and SCADA alarms (Nabız), answers from the plant’s own documents with sources (Chatbot) and produces optimization suggestions for PID loops (Verim).
Does Meridyen need an internet connection?
No. Meridyen runs offline on a server inside the plant (edge). Remote access is off by default and opens only with your approval, and every session is logged.
Does Meridyen write to the control system?
No. It only reads DCS and SCADA data. No suggestion, including PID tuning suggestions, is applied automatically; the engineer has the final say.
How does it help with DCS alarm management?
The Nabız module groups related alarms into a single situation, shows the likely root cause, gives early warning from alarm trends and assesses alarm load against EEMUA 191.
Where is our data stored?
Process data, documents and fault logs stay on your plant’s server. They are not sent to Cervoi or third parties and are never used to train models for another customer. The network layout follows IEC 62443 zones and conduits.
Does installation require a shutdown?
No. Meridyen is installed on an on-site server and connects read-only to the DCS; commissioning requires no shutdown.
Modules
THREE MODULES, ONE PLATFORM
Chatbot
A technical assistant that knows your plant.
- Answers from your own documents, with sources
- Memory of past faults and their fixes
- Answers plant questions only
Verim
Optimization for PID loops.
- Loop health score, oscillation and offset detection
- Reasoned Kp, Ti and Td suggestions
- Steadier loops, less energy lost
