Why Domain Expertise Matters

Automation Software Built by Automation Engineers

Industrial automation software is not a vertical application of general software engineering. It requires understanding of process instrumentation, control theory, communication protocols, safety interlock logic, alarm management philosophy, and the operational realities of a 24/7 plant environment where software failures have direct safety and production consequences.

Mehal Thakor's 29+ years — including 23+ years specifically building TAS and SCADA software at GE Oil & Gas, Emerson Process Management, and AST — means Ath Software understands what a field instrument is, how a PID loop behaves, why alarm floods happen, and what a reliable industrial historian architecture looks like. That domain depth makes every architectural decision in our automation software correct by default.

Our automation software projects include: SCADA for 70+ municipal STP stations, tyre industry mixing plant SCADA migration, gas metering skid web monitoring, gearbox test automation with ABB SCADA integration, and IIoT data acquisition from Siemens PLCs and 330+ energy meters.

Service Areas

Industrial Automation Software Services

Data Acquisition Software

Software that acquires data from PLCs, RTUs, smart sensors, flow computers, and field devices via OPC UA, Modbus, Ethernet/IP, and proprietary protocols. High-frequency polling (down to 500ms), exception-based reporting, data quality filtering, and robust reconnection handling for uninterrupted operation in real plant environments.

Supervisory Control & HMI

Process mimic screens, control faceplates, trend displays, and alarm management interfaces — browser-based for no-client-installation access. High-performance rendering for large tag counts. Custom graphics for specific equipment types. Role-based access control at the screen and tag level.

Alarm Management (ISA-18.2)

Alarm philosophy implementation per ISA-18.2: prioritisation, setpoint rationalisation, shelving, suppression, acknowledgement workflows, and alarm flood detection. Alarm key performance indicators — nuisance alarm rate, standing alarms, chattering alarms — with configurable alert thresholds and OPC AE export.

MES & Production Systems

Manufacturing Execution System (MES) development bridging SCADA and ERP — production order tracking, material consumption, batch records, quality parameter logging, and OEE calculation. ISA-95 standard architecture for MES/ERP integration via REST API or message queue.
