Question 1

Which Emerson platforms and products does Patrion support for SCADA & HMI services?

Accepted Answer

Patrion supports the full Emerson stack commonly found in process plants: DeltaV DCS (DeltaV Operate, DeltaV Live, DeltaV Continuous Historian, Control Studio), ROC800 series remote controllers and RTU hardware, Rosemount transmitters and instrumentation, AMS Device Manager, and related PlantWeb components. The team also integrates Emerson systems with third‑party historians like OSIsoft PI, SQL Server and OPC UA/DA clients. Support covers configuration, commissioning, graphics development, alarm management and ongoing field engineering for firmware, redundancy and network issues, following Emerson-approved procedures and compatibility matrices.

Question 2

How does Patrion implement ISA-101 HMI design on DeltaV Operate?

Accepted Answer

Patrion applies ISA-101 principles to DeltaV Operate and DeltaV Live by developing operator-centric graphics, standardized faceplates, consistent navigation and role-based screens. The process begins with operator task analysis and style-guide creation, then moves to template-based graphics, dynamic displays for abnormal situations, and validation through operator walkthroughs and simulator testing. Deliverables include HMI style guides, operator procedures embedded in screens, and measurable operator performance criteria. All HMI work is validated against ISA-101 objectives and tested in FAT/SAT before plant cutover.

Question 3

What is Patrion’s approach to ISA-18.2 alarm management in Emerson systems?

Accepted Answer

Patrion follows the ISA-18.2 alarm lifecycle: alarm philosophy, rationalization, implementation, and ongoing management. For DeltaV and ROC800 systems they perform alarm audits, root-cause analysis of nuisance alarms, rationalize alarm parameters (limits, priorities, deadbands), and configure alarm shelving, suppression and flood management. Implementation uses DeltaV Alarm Viewer and historian-backed alarm analytics. Documentation includes rationalization matrices, KPI tracking and procedures for continuing alarm management. Work adheres to ISA-18.2 and is integrated with operator training and procedural changes.

Question 4

Can Patrion integrate Emerson ROC800 controllers with central historians and SCADA via OPC?

Accepted Answer

Yes. Patrion configures ROC800 data points and exposes them to central SCADA and historians using supported protocols such as OPC DA/UA, Modbus TCP/RTU and native Emerson connectivity. The service includes tag mapping, timestamp synchronization, data compression and retention policy design. Integration outputs support DeltaV Continuous Historian, OSIsoft PI System (via OPC or PI Interfaces), and SQL Server/SSRS for reporting. The team verifies data integrity end-to-end and implements secure communications per IEC 62443 when connecting remote sites.

Question 5

What on-site services does Patrion provide for ROC800 commissioning and troubleshooting?

Accepted Answer

Patrion’s field engineers offer hands-on ROC800 services including hardware installation, I/O checkout, firmware upgrades, controller logic verification in the ROC800 programming environment, network configuration, and end-to-end I/O loop testing. They perform FAT/SAT, redundancy failover testing and on-site troubleshooting for communications (Modbus, OPC, HART), and coordinate spares and firmware rollbacks as needed. All commissioning activities are documented with test scripts and traceable acceptance criteria; security hardening follows IEC 62443 guidance for remote access.

Question 6

How does Patrion handle HMI modernization from legacy SCADA to DeltaV?

Accepted Answer

Patrion conducts a phased modernization: asset discovery, legacy screen inventory, operator task analysis and prioritized migration plan. They create DeltaV graphics templates (DeltaV Live/Operate), transfer and rationalize alarms per ISA-18.2, and validate operator workflows via simulators and FAT. Cutover is staged with rollback plans and parallel operations to minimize production impact. Training and updated procedures are delivered with the HMI package. For integration risks, Patrion uses tag mapping tools and verifies historian continuity with PI or DeltaV historian solutions.

Question 7

What cybersecurity standards and practices does Patrion apply to Emerson SCADA/HMI projects?

Accepted Answer

Patrion implements defense-in-depth and follows IEC 62443 and NIST SP 800-82 for industrial control system security. Measures include network segmentation, firewalls, jump server access, hardened operator workstations, secure OPC/OPC UA configurations, patch management, and secure firmware handling for DeltaV and ROC800 devices. They perform vulnerability assessments, secure configuration baselining, and provide documented cybersecurity procedures and incident response plans aligned with ISA/IEC guidance and customer governance requirements.

Question 8

What historian, reporting and dashboard technologies does Patrion use with Emerson systems?

Accepted Answer

Patrion configures DeltaV Continuous Historian for local trending and integrates Emerson data into OSIsoft PI System or SQL Server for enterprise reporting. They deliver SSRS, Power BI or PI Vision dashboards and implement PI Integrators or OPC UA feeds for analytic-ready datasets. Services include tag mapping, compression/archiving policies, KPI development, and automated report generation. Data validation, timestamp alignment and historian redundancy are part of the implementation, ensuring regulatory-grade audit trails where required (e.g., ISA-95 integration).
