Pumps & motors
Start, stop, status, permissive, interlock and fault information can be coordinated with the operating sequence.
PLC engineering
Control logic built around operating intent.
PLC engineering begins with the process, equipment relationships and required operating states. Architecture, I/O and software are developed together so sequences, permissives, interlocks, alarms and fail-safe behaviour remain traceable through testing and commissioning.
01
Control architecture
Controllers, distributed I/O, networks and interfaces are structured around the process and operating requirements.
02
I/O mapping
Signals are organized against field devices, equipment interfaces, control functions and testing requirements.
03
Logic & sequencing
Operating sequences, permissives, interlocks, alarms and fail-safe responses are translated into maintainable control logic.
04
Testing & commissioning
Software and field operation are verified against the defined control intent and available equipment interfaces.
SCADA & HMI
Operational information arranged for clear supervision.
HMI and SCADA environments organize process graphics, equipment status, alarms, trends, events, setpoints and commands around the way operators need to understand and control the system. User access can be structured where supported and required by the project.
- Operator interfaces
- Process graphics
- Alarm handling
- Trends and event visibility
- Setpoints and commands
- Status monitoring
- User access where applicable
Communications & integration
Interfaces selected for the installed equipment and required architecture.
Industrial integration may connect controllers, distributed I/O, drives, instruments, package equipment and supervisory systems. Protocol and gateway selection is project-specific and depends on supported interfaces, network topology, performance requirements and the installed equipment.
Connected Operations- Modbus TCP
- Modbus RTU
- BACnet where applicable
- OPC / OPC UA where supported
- EtherNet/IP where supported
- PROFINET where supported
- Serial communications
- Third-party gateways
Industrial control systems
Control coordinated across plant and equipment interfaces.
PLC and SCADA systems can coordinate pumps, motors, variable-frequency drives, process equipment, utility systems and compatible packaged equipment within the defined automation scope.
VFD-controlled equipment
Supported drive commands, speed references, operating status and faults can be integrated with PLC and supervisory systems.
Process & utility systems
Control logic can coordinate equipment relationships, measurements and operating modes within the defined process scope.
Package-equipment interfaces
Compatible packaged systems can be integrated through available hardwired or communication interfaces.
Testing & commissioning
Verification from field signal to supervisory operation.
Commissioning checks the relationship between field devices, I/O, control logic, communications and operator interfaces. The applicable test scope depends on project responsibilities, equipment readiness and available interfaces.
- I/O checks
- Field-device verification
- Logic testing
- Interlock testing
- Alarm testing
- Communication testing
- HMI / SCADA verification
- Site commissioning
Retrofit & migration
Modernization planned from the existing system outward.
Retrofit work begins with the installed PLC, software, I/O, control panels, communications and supervisory environment. Migration may be staged, but direct reuse or migration is never assumed; compatibility, available backups, operating constraints and project requirements determine the approach.
- Existing PLC assessment
- Logic and I/O review
- Panel and interface review
- Staged migration planning
- Controller replacement
- SCADA upgrade
- Recommissioning
Technology context
Industrial technologies selected around the application.
Confido works with industrial automation technologies including Beckhoff, Honeywell Saia Burgess Controls (SBC) and Siemens. Platform, controller and interface selection depends on the required architecture, installed equipment and project scope.

Manufacturer names identify technologies Confido works with and do not imply an additional commercial relationship.
Troubleshooting & lifecycle support
Support grounded in the installed control environment.
Troubleshooting and lifecycle work is defined around the accessible controller, software, communications, I/O and supervisory system. Modifications and upgrades remain subject to approved scope, compatibility and available system records.
Controller diagnostics
Controller state, accessible diagnostics and program behaviour are reviewed against the reported operating issue.
Communications & I/O
Network, interface, I/O and field-signal faults are investigated within the agreed system boundary.
Logic & supervision
Control logic, alarms, graphics and HMI or SCADA behaviour can be reviewed and modified within an approved scope.
Backups & upgrades
Available software and configuration backups can be reviewed to support recovery planning, modifications and future upgrades.
