New control system
Define control narratives, I/O, sequences, alarms, operator interfaces, communications, and test criteria for a new process.
Industrial automation & process control
PLC controls built around your water process.
Plan new controls, modernize an existing system, troubleshoot faults, or connect water-treatment equipment to the wider plant architecture.
- PLC logic and control narratives
- HMI, alarms, trends, and operator workflow
- SCADA and equipment integration
- Testing, commissioning, and handover
The initial discussion identifies missing documentation and determines whether remote preparation, a site review, or a larger modernization scope is appropriate.
Project fit
Four common reasons to bring controls into the conversation
The first step is to understand whether the core need is new implementation, migration, fault diagnosis, or integration.
Modernization & migration
Review existing hardware, software access, backups, compatibility, spare capacity, shutdown windows, and a safe migration path.
Troubleshooting
Document symptoms, fault history, operating conditions, recent changes, and the boundary between controls and process equipment.
Plant integration
Define required data points, protocols, ownership, cybersecurity constraints, testing responsibilities, and handoff to other systems.
Controls scope
One operating system, several connected disciplines
A reliable scope connects the process sequence, field devices, operator decisions, plant communications, testing, and documentation.
PLC logic
Sequences, interlocks, permissives, modes, alarms, equipment control, and process-specific logic.
HMI & operator workflow
Status, commands, setpoints, alarm context, trends, and screens organized around real operating tasks.
Communications & I/O
Instrumentation, remote I/O, drives, packaged equipment, supported protocols, and defined integration boundaries.
SCADA, data & reporting
Tags, trends, events, historian requirements, reports, and escalation paths based on the plant architecture.
Testing & commissioning
Test plans, simulations where appropriate, site acceptance, fallback steps, commissioning support, and issue tracking.
Prepare the first review
Useful project information
Send what is available. Gaps can be logged and resolved before implementation commitments are made.
- Process objective and current operating sequence
- PLC, HMI, drives, instruments, and network information
- Available drawings, backups, source code, and passwords
- Known faults, recent changes, and production impact
- Required data exchange and third-party responsibilities
- Shutdown, access, safety, validation, and commissioning constraints
Controls project discussion
Describe the process, current platform, and change you need.
Share the equipment, available documentation, known issues, integration requirements, and commissioning constraints. A specialist will help define the next review step.
- Scope and documentation gaps
- Integration and commissioning questions
- A project-specific next step
Delivery approach
Controls changes need a testable plan
Exact activities depend on platform access, site conditions, safety requirements, and the approved project boundary.
- 01
Discover
Review the process, current controls, available documentation, site constraints, and the business reason for the change.
- 02
Define
Agree on scope boundaries, control philosophy, interfaces, deliverables, test criteria, responsibilities, and change risks.
- 03
Build & test
Develop against the approved scope, document assumptions, and complete the agreed bench or offline testing before site work.
- 04
Commission & hand over
Execute the site plan, record issues, confirm acceptance criteria, and provide the documentation and operator handover included in scope.
Also planning the treatment equipment or installation?
Connect the controls scope to the wider commercial water project.
Common questions
PLC & controls project questions
The information needed to evaluate upgrades, integration, troubleshooting, and commissioning work.
What should I provide for an initial controls review?
Share the process objective, existing PLC and HMI brands, available drawings, I/O information, communications, known faults, and the required commissioning window. Missing information can be identified during the first scope discussion.
Can an existing PLC or HMI be upgraded?
Often, but the answer depends on hardware condition, software access, backups, spare capacity, communications, safety requirements, and compatibility with the proposed changes. The existing system must be reviewed before an upgrade path is confirmed.
Do you integrate with SCADA and other plant systems?
Integration can be scoped for supported protocols and existing plant architecture. Required data points, ownership boundaries, cybersecurity requirements, and testing responsibilities are defined before implementation.
How is commissioning planned?
Commissioning planning covers test procedures, operating constraints, shutdown windows, fallback steps, responsible parties, documentation, and operator handover. The plan is specific to the process and site.
Can you troubleshoot an operating system?
Troubleshooting can be discussed when the controls platform, symptoms, site access, and safety conditions are known. The first review determines whether remote preparation, an on-site assessment, or a larger modernization scope is appropriate.
