Control Expert includes a collection of modules and devices—called the Hardware Catalog—that you can add to a Control Expert project. EtherNet/IP and Modbus TCP devices are located in the hardware catalog’s DTM Catalog page. Each device in the catalog is represented by a DTM that defines the parameters of the module or device.

Not every device on the market today offer device-specific DTMs. Some devices are instead defined by a device-specific EDS file. Control Expert displays each EDS file in the form of a DTM. In this way, you can use Control Expert to configure these Ethernet/IP devices—defined by an EDS file—in the same way you would configure a DTM-defined device.

Other devices lack both a DTM and an EDS file. You can configure these devices by using a Generic DTM that is included in the DTM Catalog page.
