SCADA modernization — Wonderware, PI, AVEVA, FactoryTalk to cloud
S2 Data Systems modernizes SCADA, historian, and OT environments without ripping out the existing control system. We bridge OSIsoft PI, AVEVA Wonderware, Rockwell FactoryTalk Historian, Siemens, and Ignition into the customer's cloud — unified by ISA-95 information models, governed by OT-safe security architectures, and ready for analytics, ML, and BI.
What we build
OPC-UA & historian bridges
Stream tags from PI, AVEVA, FactoryTalk, Ignition, Kepware into Kafka, Kinesis, or Event Hubs.
ISA-95 information models
Tag taxonomy, equipment hierarchies, unit-of-measure dictionaries layered on top of raw historian data.
OT/IT segmentation
Data diodes, jump hosts, segmented VPCs, audit logging — preserving the OT security boundary.
Time-series + warehouse storage
TimescaleDB / InfluxDB / Databricks Delta for high-frequency tags; Snowflake / BigQuery for analytics queries.
Compliance reporting
Auditable pipelines aligned to NERC CIP, IEC 62443, NIST SP 800-82 where required.
Closed-loop integration (where safe)
Bidirectional flows for analytics to write back into SCADA — guarded by command authorization and rollback.
Reference stack
Outcomes our Utah clients see
- Real-time KPIs across plants instead of monthly reports
- Predictive maintenance models trained on 5+ years of historian data
- Energy and OEE benchmarks across like-for-like equipment
- Compliance reporting that pulls audit-ready data automatically
- OT/IT-segmented architecture that satisfies enterprise security review
Frequently asked questions
Will SCADA modernization disrupt my plant?
No. S2's approach is non-intrusive: OPC-UA bridges and one-way historian-to-cloud streams. The SCADA system itself is unchanged; we add a parallel data plane that the cloud reads.
Do I need to replace OSIsoft PI or AVEVA Wonderware?
No. We bridge them. The historian remains your operational system of record; the cloud becomes the analytics and ML system of insight.
How do you handle Utah's regulated industries (oil & gas, utilities, mining)?
Architectures align to NERC CIP, IEC 62443, NIST SP 800-82, and customer-specific security policies. Data diodes, segmented VPCs, audit logging, and access reviews are built in from day one.
