The deal adds industrial data connectivity, historization and visualization to SeQent's alarm notification and communication portfolio.
SeQent announced the acquisition of Open Automation Software (OAS), an industrial data connectivity company whose platform moves data between controllers, databases, and cloud services regardless of vendor. The acquisition extends SeQent’s portfolio upstream, from alarm notification and escalation into edge-to-cloud connectivity, data movement, historization, and visualization.
SeQent’s platform ingests alarms and events from SCADA, MES, and PLC systems, applies routing and escalation rules, and delivers notifications to two-way radios, smartphones, displays, and PA systems. OAS adds the layer beneath it: native drivers for Allen-Bradley and Siemens controllers, Modbus devices, and OPC servers, store-and-forward buffering across machines, lines, and sites, and high-speed logging into customer-owned databases.
At the heart of the OAS Platform is the Universal Data Connector, which moves data from anywhere to anywhere: from an Allen-Bradley PLC to a Siemens PLC, from a PLC to a database, from a database into visualization. Open protocols, edge compute, and the Unified Namespace (UNS) spanning OT and IT are reshaping how plants move data. OAS is built for that architecture without locking a plant into a single vendor’s stack. SeQent applies the same principle after detection, delivering to any device or channel a plant runs on. A plant running four generations of equipment from three vendors gets one path in and one path out, with no requirement to standardize on either end.
With OAS, SeQent delivers:
- Notification from any source – Legacy controllers, Modbus devices, MQTT sources, and databases drive the same routing and escalation rules as SCADA and PLC alarms.
- One auditable record – The data that triggers an escalation is logged in an open format to the customer’s own database, alongside the process data that produced it and the record of who was notified and whether they acknowledged.
- Fewer components in the critical path – No third-party integration layer between the device that produces a signal and the person who acts on it.
- Signal to action, end to end – Connectivity and historization from OAS, routing and response from SeQent, on one path from the device to the person who resolves it.
Both companies count Fortune Global 500 manufacturers among their customers in automotive, data centers, pharmaceuticals, and consumer packaged goods. Several run SeQent and OAS side by side today. With OAS, SeQent’s platform spans connectivity, aggregation, and response: everything between a signal on the plant floor and the person who resolves it, with no handoff between vendors in the middle.
