SeQent buys Open Automation Software to link plant data to action
What's the deal? SeQentDealroom has a profile for this one. Try Dealroom →, a provider of industrial alarm notification and plant-floor communication software, has acquired Open Automation SoftwareDealroom has a profile for this one. Try Dealroom → (OAS), an industrial data connectivity company. Terms were not disclosed. The deal, announced September 10, 2026, extends SeQent's portfolio upstream into edge-to-cloud connectivity, data movement, historization, and visualization.
What does each side do? SeQent ingests alarms and events from SCADA, MES, and PLC systems, applies routing and escalation rules, and delivers notifications to devices like two-way radios, smartphones, and PA systems. OAS adds the layer beneath: native drivers for Allen-BradleyDealroom has a profile for this one. Try Dealroom → and SiemensDealroom has a profile for this one. Try Dealroom → controllers, Modbus devices, and OPC servers, plus store-and-forward buffering and high-speed logging into customer-owned databases.
What's the endgame? The combined platform aims to span connectivity, aggregation, and response — everything between a signal on the plant floor and the person who resolves it. At the core of OAS sits the Universal Data Connector, which moves data from any source to any destination, including PLC to PLC, PLC to database, and database to visualization.
Why now? Open protocols, edge compute, and the Unified Namespace spanning operational and IT systems are reshaping how plants move data. OAS is built for that architecture without locking a plant into a single vendor's stack, and SeQent applies the same principle after detection.
What they're saying: "Getting data out of the plant and getting a person to act on it have always been sold as two separate problems, by two separate vendors," said Sheret Ross, co-chief executive officer of SeQent. "Adding OAS to our business closes that gap."
Ken Eldridge, president of OAS, framed the fit differently. "We built OAS so that a plant's data belongs to the plant, in an open format, in the customer's own database," he said, adding that alerting a human in time is "the problem SeQent has spent three decades on."
The signal: Both companies count Fortune Global 500 manufacturers among their customers in automotive, data centers, pharmaceuticals, and consumer packaged goods, and several already run the two products side by side. The deal reflects a broader push to consolidate fragmented industrial software, giving plants one path in and one path out across mixed-vendor equipment.
