Page 3: General
Kemppi's Digital Connectivity Module (DCM) is a small single-board computer connected directly to the welding power source or wire feeder. Together with the Kemppi Cobotics application, it forms a connection between the welding equip- ment and robot / cobot (collaborative robot) via the Modbus TCP fieldbus (in the setup, DCM is a Modbus TCP slave device). -

Page 7: Mounting On Equipment
DCM Kemppi Cobotics Operating manual - EN 2.1 Mounting on equipment The DCM device can be fixed on the side of a power source or a wire feeder either with the factory-fitted mounting tape or with an optional DIN rail. - Page 8 DCM Kemppi Cobotics Operating manual - EN Let the mounting tape's adhesive cure for 30 minutes. Due to the velcro-type mounting tapes, it is now possible to detach and attach the DCM device if needed. Mounting on DIN rail (optional) Note that the rail installation typically requires drilling fixing holes on the fixing surface for the rail itself.

Page 9: Connecting Cables
DCM Kemppi Cobotics Operating manual - EN 2.2 Connecting cables The DCM requires a CAN and an Ethernet cable to be connected. It is recommended to use a shielded Ethernet cable (minimum F/UTP – foil shielded / unshielded twisted pair). -
Page 10: Installing Kemppi Cobotics Application
Welding settings are configured in the welding system's control panel. For Kemppi Cobotics application, a DCM firmware version 1.00.92.0 or newer is required. (For welding equipment firm- ware versions, refer to "General" on page 3.) Scan the QR code below or search for 'Kemppi Cobotics' in Google's Play Store. -
Page 11: Connecting Fieldbus Converter (Optional)
DCM Kemppi Cobotics Operating manual - EN 2.4 Connecting fieldbus converter (optional) The fieldbus converter changes the Modbus TCP fieldbus connection into an Ethernet/IP connection. Install the fieldbus converter by connecting it to the DCM and e.g. the cobot controller with two Ethernet cables. Then configure the cobot to communicate with the fieldbus converter (refer to the cobot controller's operating manual). - Page 12 The following lists the fieldbus converter's preconfigured configuration settings that are used for the communication between the cobot and the fieldbus converter. Parameter Value Description 192.168.127.254 IP address of the fieldbus converter delivered by Kemppi. IP address Vendor ID of the fieldbus converter. Vendor ID Device type Device type of the fieldbus converter.
