Installs as an independent Windows service. It can run on a dedicated communications server, an edge gateway, or directly on an HMI node.
KEPServer Enterprise is a specialized, rebranded, and tightly integrated version of KEPServerEX developed specifically for Rockwell Automation environments. The Rockwell Partnership Driver Availability and Protocol Support A Modbus suite
Deciding between the two ultimately comes down to your plant's operational strategy and installed base:
: While KEPServerEX offers a vast suite of over 150 drivers, KEPServer Enterprise typically focuses on the drivers most relevant to Rockwell's ecosystem, though it still provides broad connectivity to third-party PLCs like Siemens or Modbus devices. When to Choose Each
: Every version of KEPServer Enterprise corresponds to a specific equivalent version of KEPServerEX . For example, if you are moving from a standard Kepware installation to a Rockwell environment, you must check the Rockwell Compatibility Matrix to ensure driver and .PFE file compatibility.
