Engineering ConsultingMove the controls forward.
Keep the operation in view.
Legacy PLC, HMI, and SCADA migration starts with understanding what is running, what must be preserved, and what production can accommodate.
Understand before replacing
The running system holds more than its program.
A control system carries operating behavior, historical decisions, alarm handling, network dependencies, and the knowledge of the people who use it. Replacing hardware requires understanding those connections.
EA&ID works across current and legacy platforms, from a panel retrofit to a multi-year migration. We assess the installed base, document the application, and plan the work around the customer’s operating goals and production schedule.
Our food-manufacturing and supply-chain experience informs that work, alongside engagements with other industrial clients whose systems span generations.
Plan the migration around
- Installed hardware, software, I/O, and network dependencies
- Available source, exports, backups, and documentation
- Required operating behavior and operator knowledge
- Supportability, spares, and obsolescence
- Production windows, commissioning, and rollback
Dependability is part of the scope
Design for the cutover.
And the years after it.
Maintainable applications
Readable control code, consistent structure, useful alarms, and HMI behavior built for the people operating the line.
Security in context
Segmentation, secure remote access, and hardening scoped to the systems we engineer or maintain under the owner’s authorization.
Resiliency and recovery
Failover, health monitoring, verified backups, and recovery procedures selected for the operating requirements of the system.
A planned handover
Cutover and rollback planning, commissioning support, as-built documentation, and project files the customer can maintain.
Plan before the failure
