Brand: Honeywell

Question 1

What deliverables does Engineering Service produce for a Honeywell Experion PKS SCADA/HMI project?

Accepted Answer

Engineering Service delivers a complete documentation and test package that typically includes: requirements and functional specification, control narrative and sequence-of-operations, I/O list mapped to field devices, alarm matrix and rationalization (ISA-18.2/EEMUA 191), operator graphic standards and faceplate libraries for Experion HMI, communications matrix (OPC UA/DA, Modbus, HART), FAT/SAT test protocols with traceable requirements-to-test matrices, and maintenance/runbooks. All software is version-controlled and delivered with backups suitable for deployment into Experion PKS servers and Uniformance PHD historian environments. The approach aligns with IEC 61131-3 coding practices and ISA-95 integration models.

Question 2

How does the firm integrate Experion PKS with third-party PLCs and historians?

Accepted Answer

Integration is performed using supported protocols and gateways—OPC UA/DA for bi-directional data exchange, Modbus TCP/RTU for legacy PLCs, HART for device-level diagnostics, and DNP3 for select utilities. For historians, Engineering Service configures Uniformance PHD when specified, or integrates third-party historians via OPC UA or historian-native collectors. The team implements mapping, data quality checks, timestamp alignment, and compression policies to meet ISA-95 data requirements and maintain historian integrity.

Question 3

Can Engineering Service perform virtual commissioning and operator training for Experion PKS?

Accepted Answer

Yes. The firm uses Experion simulation mode and in-house simulation harnesses to perform virtual commissioning that exercises logic, graphics, alarm handling, and historian flows prior to site work. Operator Training Simulator (OTS) environments are built from the same application codebase to provide realistic training scenarios. This reduces onsite commissioning time and improves operator readiness. Virtual commissioning activities are validated by scripted FAT protocols and traceable test evidence.

Question 4

What cybersecurity measures are implemented for Honeywell SCADA/HMI projects?

Accepted Answer

Engineering Service designs systems in accordance with IEC 62443 and NIST SP 800-82 guidance: network segmentation, VLANs, DMZs for historian/MES interfaces, hardened Windows Server and domain configurations, role-based access control, multi-factor authentication where supported, and secure remote access with VPN and jump servers. Patch management, audit logging, and change control are documented in the security plan and baseline configuration. The firm also supports Honeywell PKS security features such as secure communications and certificate management where applicable.

Question 5

How are FAT and SAT executed for Experion PKS projects?

Accepted Answer

FAT is executed in a controlled factory environment or hosted lab using the actual Experion PKS application and simulated I/O. Engineering Service prepares detailed FAT scripts derived from the functional specification and executes them with customer witnesses, capturing pass/fail evidence and results logs. SAT repeats critical tests onsite under field-connected conditions, validates I/O mapping, network performance, and real-world alarm and sequence behavior. Both FAT and SAT adhere to documented test protocols and supply a final acceptance report.

Question 6

Does the firm provide alarm management and ISA-18.2 compliance services?

Accepted Answer

Yes. Engineering Service conducts alarm philosophy development, alarm rationalization and prioritization against ISA-18.2 and EEMUA 191 practices, implements alarm shelving, suppression, and dynamic alarming in Experion HMI, and configures alarm flood protection and annunciation. Deliverables include an alarm philosophy document, rationalized alarm lists, HMI changes, and verification testing to demonstrate reduced nuisance alarms and improved operator situational awareness.

Question 7

What long-term support and SLA options are available for Experion PKS systems?

Accepted Answer

Support options include remote diagnostics and patch deployment, 24/7 on-call support, scheduled preventive maintenance, configuration backups, and on-site corrective services. SLAs are scoped by response time (e.g., critical 4-hour on-site or remote triage), contract hours, and coverage for software updates or minor application changes. Engineering Service can also coordinate Honeywell-supplied spare parts and lifecycle planning to align with vendor support windows.

Question 8

What are the main cost and timeline drivers for Honeywell SCADA & HMI projects?

Accepted Answer

Primary drivers are project scope (number of I/O points, alarm count, and number of graphics/screens), integration complexity (third-party PLCs, MES, historians), high-availability requirements (server/controller redundancy), cybersecurity and network isolation needs, and FAT/SAT logistics. Virtual commissioning and reuse of faceplate libraries reduce schedule and cost. A small skid-level implementation can be delivered in weeks; multi-site enterprise rollouts with redundancy and MES integration can span several months. Detailed scoping and a functional spec reduce schedule risk and procurement uncertainty.
