PTC Kepware

PTC Kepware (the KEPServerEX product, plus ThingWorx Kepware Edge and Kepware+) is the dominant industrial-connectivity gateway product on the market — over 150 protocol drivers spanning Modbus, Profinet, Ethernet/IP, S7, BACnet, and OPC UA, exposed through a unified server / namespace. PTC acquired Kepware in 2016 (~$100M) as the OT-side complement to ThingWorx.

Context

Kepware ships in three deployment modes: KEPServerEX (Windows server, the historical product), ThingWorx Kepware Edge (lightweight Linux container for edge gateways), and Kepware+ (cloud-managed). It is widely deployed even outside PTC ecosystems as the canonical multi-protocol OT bridge.

What it implements

• Industrial Connectivity — the flagship product in this category.
• IoT Platform — feeds ThingWorx and other IIoT platforms with normalized telemetry.

Relationships (see sidebar)

• Competes with Siemens Brownfield Connect in industrial-connectivity deals; and AVEVA, Inductive Automation Ignition, and OPC UA-native PLC stacks.

Vendor

PTC, Inc. (acquired Kepware Technologies, 2016).
