dataFEED uaGate 840D


uaGate 840D – Gateway for SINUMERIK 840D Solution. Addition of an OPC UA server for the integration of data to an MES
HS Code: 85176200
Weight: 0.400 kg

SKU: GAA-YX-145144 Categories: , , , ,



This gateway allows the reading of all data from the SINUMERIK 840D machine tool. It can also access the NC parts with its axis, tool, program and data, as well as specific alarms. In addition, a connection to the SIMATIC Siemens S7 can be established. The data from the 2 connections is available via the OPC UA and the MQTT interface and can be used for “Industry 4.0 Applications”

With the uaGate 840D gateway, important spindle and axis data such as torque and power consumption can be read and reused for many applications. currently used tool are accessible. For example, this data is available for condition monitoring, predictive maintenance, for data logging, or for analysis tasks, such as spindle and axis monitoring. The gateway can also be used to acquire data from older SINUMERIK 840D controllers. Thanks to the preconfigured data symbol file for the standard use case based on one channel, three axes and one spindle, the user does not need any specific SINUMERIK know-how for reading the data.

The product can simply be mounted next to the SINUMERIK NCU on a DIN rail and requires a 24 VDC power supply. It has two independent Ethernet interfaces, one addressing the machine and the other the computer network. Between these, the gateway acts as a firewall. Setup is just a few clicks away using any web browser and the built-in web server
