Smarter Industrial Control Starts with the Right Automation System
Dayma Infotech helps businesses explore industrial control and automation solutions for new installations, existing machinery and production-line upgrades. From PLC programming and HMI configuration to control-panel development, SCADA visualisation and system modernisation, these technologies help coordinate machine operations and improve visibility into industrial processes.
Whether a business is developing a new automated system or upgrading obsolete controls, the right approach depends on its equipment, operational requirements, safety considerations and integration needs.
Connect Machines, Operators and Process Data
PLC, HMI and SCADA technologies work together to control equipment, display operating information and monitor industrial processes.
- PLC (Programmable Logic Controller): Executes programmed control logic to manage machine sequences, inputs, outputs and connected equipment.
- HMI (Human-Machine Interface): Gives operators a visual interface to monitor machine status, view alarms and interact with supported controls.
- SCADA (Supervisory Control and Data Acquisition): Provides supervisory monitoring, process visualisation, alarms and data logging across connected equipment or facilities.
When appropriately designed and integrated, these technologies can help businesses manage operations more consistently and make better-informed decisions.
Our PLC, HMI & SCADA Capabilities
Dayma Infotech can help businesses explore industrial automation and control-system options for manufacturing, material handling, utilities and process applications.
- New Control Panels: Explore control-panel solutions designed around machine requirements, electrical components, I/O requirements and operating conditions.
- PLC Programming and Configuration: Develop or modify control logic for machine sequencing, process control, interlocks and equipment coordination, subject to project scope.
- HMI Design and Configuration: Create operator screens for machine status, process values, operating commands, alarms and other relevant information.
- Obsolete PLC and HMI Retrofitting: Assess options for replacing outdated controllers and operator interfaces while considering existing wiring, logic, communications and equipment compatibility.
- SCADA Screens and Visualisation: Present process status, operating values and connected equipment information through configured supervisory screens.
- Alarm Management: Configure alarm indications, priorities and event records to help operators identify and respond to abnormal conditions.
- Data Logging and Reporting: Capture selected process values, machine events and operating history where supported by the system.
- System Integration and Upgrades: Explore connectivity between PLCs, HMIs, SCADA software, sensors, drives and other compatible industrial devices.
“A well-designed control system connects machine logic, operator visibility and process data into one coordinated operational environment.”
Control Better. Monitor Smarter. Upgrade Confidently.

Modernise Your Control Systems for Changing Requirements
Industrial control systems often remain in service for years. Over time, older controllers, discontinued HMIs and unsupported software can create maintenance challenges, integration limitations and difficulties obtaining replacement parts.
A structured upgrade can help businesses assess current control architecture and plan improvements while considering operational continuity.
Dayma Infotech can help businesses explore options for:
- Developing control-system concepts for new machines and production lines.
- Reviewing obsolete PLCs, HMIs and related automation components.
- Planning controller and operator-interface replacements.
- Improving machine-status displays and operator workflows.
- Configuring process alarms and event logging.
- Connecting compatible control equipment with monitoring or reporting platforms.
- Planning phased upgrades to reduce disruption during implementation.
The final solution should be based on the machine's control requirements, electrical design, communications protocols, software compatibility, cybersecurity needs and applicable safety requirements.
Important: PLC, HMI and SCADA systems that perform safety-related functions require appropriate safety engineering and validation. Standard control logic should not be treated as a substitute for a properly designed safety system.
Frequently Asked Questions About PLC, HMI & SCADA
A PLC executes control logic, an HMI provides a visual interface for operators, and SCADA enables supervisory monitoring, alarm management and data collection across connected equipment or processes.
Often, yes. Replacement requires reviewing the existing controller, program, I/O configuration, communications, connected devices and operating requirements to determine a suitable migration approach.
It may be possible if the devices support compatible communications protocols, data addressing and required functionality. Compatibility should be confirmed before selecting replacement equipment.
Depending on its configuration, SCADA can display equipment status, process measurements, alarms, trends, historical data and other information from connected industrial systems.
Yes. Compatible systems can capture selected machine states, process values and events for monitoring, logging and reporting. The available data depends on instrumentation and integration.
Start by documenting the existing system, PLC and HMI models, available programs, I/O lists, communications, operating sequences and required improvements. A technical assessment can then establish the migration scope, testing plan and implementation approach.
