Kepware Server and ThingWorx

A common challenge at manufacturing sites in India is rushing into visualization while leaving equipment connectivity for later. This article explains whether you should use Kepware Server, ThingWorx, or both within the Velotic product portfolio.

What Is the Difference Between Kepware Server and ThingWorx?

Kepware Server connects shop-floor equipment, PLCs, and applications, standardizes the data, and passes it to upper-level systems. ThingWorx is an IIoT platform that handles visualization, analysis, and application development using collected data to support operational improvement. The difference is whether the focus is on collecting data or using it.

Kepware Server and ThingWorx: Quick Comparison

Kepware Server helps shop-floor teams establish connections with equipment, while ThingWorx helps managers analyze data and use it for operational improvement. Keep in mind that they are used in different phases and by different users.

Roles in Mixed Environments

In mixed environments, the two products come into play at different stages. Kepware Server is strongest at the stage of extracting data from equipment made by different manufacturers. ThingWorx creates value at the stage of visualizing collected data across the plant and linking it to comparison and improvement actions. When Japanese-made PLCs are part of the mix, there may also be room to consider a Japanese-made OPC server at the connection layer.

What Should You Validate in a PoC?

Even in a pre-implementation PoC, you need to separate the objectives. For Kepware Server, which handles communication, validation focuses on confirming whether data can be acquired stably. For ThingWorx, validation checks whether visualized screens and analysis results are useful for shop-floor operations and business improvement.

Which Should You Implement?

The answer depends on whether your challenge is connecting equipment or using the data after it is connected. If you want to move seamlessly from connectivity through visualization and analysis, consider combining both products.

Kepware Server is an industrial connectivity tool, while ThingWorx is an IIoT utilization tool. Understanding each product’s area of strength is a practical shortcut to project success.

Both products had been offered under the PTC brand, but in March 2026 the Kepware and ThingWorx businesses were sold to a TPG affiliate and incorporated into the portfolio of Velotic, an independent industrial software company formed by combining them with GE Vernova’s former Proficy business^*.

When Japanese-made PLCs are installed on the shop floor, adopting a Japanese-made OPC server at the communication layer can often make configuration work and later maintenance smoother. The article below explains how to choose an OPC server that fits your project requirements and introduces recommended products. Please use it when comparing and evaluating options.
