PLC and Controls: engaged alongside the core practice.
Supporting capability in controls and PLC programming. Allen Bradley, Siemens, Modicon, and Emerson platforms. Application code, HMI development, safety system logic review, and DCS integration. Engaged alongside consulting, project management, and integration.
PLC and Controls: in depth.
Controls and PLC programming at Nelvamar is a supporting capability that complements our industrial consulting and project management practice. When an owner's scope requires new PLC application code, an HMI rebuild, a safety instrumented system logic review, or DCS integration support, Nelvamar can engage that work as part of the broader project scope. Platforms covered include Allen Bradley ControlLogix and CompactLogix, Siemens S7 and TIA Portal, Schneider Modicon, and Emerson DeltaV and Ovation. Application code, structured text, ladder logic, and function block are all in scope. We do not position this as a standalone controls integration firm. We deliver controls capability where it serves the owner's technical and project interests, under the same VP level leadership and senior technical professional accountability that governs every engagement.
What you receive from this engagement.
Every engagement produces specific, auditable deliverables. These are representative outputs; the exact scope is agreed at kickoff and documented in a scope memo.
PLC and Controls
Deliverables are produced to the standards owners audit against. Revision histories, comment and response tracking, and basis of design documentation are standard practice.
- PLC application code development and review
- HMI and SCADA screen development
- Safety instrumented system logic review
- DCS integration and migration technical support
- Controls narrative and logic description documentation
- Factory acceptance test planning and execution support
- Site acceptance testing and loop verification
Define, deliver, defend.
Three steps that protect the owner's technical position from scope definition through delivery.
Scope memo first
Before work begins, we document the deliverables, interfaces, timeline, and technical assumptions. The scope memo is the reference document for every subsequent decision.
Senior staff on every engagement
VP level leadership and senior project and technical staff deliver the work. No anonymous outputs, no handoffs without accountability.
What we can defend
Every deliverable is produced to the standard that Nelvamar's senior technical professionals can defend in front of an owner, an auditor, or a startup team.
