Operating manual - EN
1. 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).
DCM uses wireless Bluetooth technology for communicating with the mobile device.
DCM for Cobotics is compatible with the following Kemppi welding equipment:
•X5 FastMig (Auto, AP and APC control panels)
>> Firmware version: 1.44
•Master M 353, 355
>> Firmware version: 1.10

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.
The mounting tape can be used on any clean and suitable surface. The mounting tape counterparts are attached
together on delivery.
Do not detach the mounting tape counterpart from the DCM device before fixing. This way the mounting tape coun-
terparts are positioned correctly on the installation surface.
Install the DCM device the connectors facing down. This also prevents e.g. dust and impurities from getting into the
connectors.
Fixing with mounting tape
1. Clean the installation surface (where the DCM device is to be fixed).
2. Remove the cover wrappings from the mounting tape counterpart to reveal the adhesive surface. Leave the mount-
ing tape counterparts still attached.
3. Press the DCM device firmly against the installation surface so that the glue sticks.

4. Let the mounting tape's adhesive cure for 30 minutes.
5. 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. This is not
covered by this instruction.
The rear of the DCM box has a groove for the standard DIN rail fixing:

2.2 Connecting cables
The DCM requires a CAN and an Ethernet cable to be connected.
Unused DCM connectors are covered. Leave the covers in place.
1. Connect the CAN cable to the power source or wire feeder.
2. Connect the other end of the CAN cable to the DCM (1). Secure the cable by turning the cable coupling firmly on
the connector threads.
3. Connect the Ethernet cable to the DCM (2). Connect the other end of the Ethernet cable to e.g. the robot controller.

2.3 Installing Kemppi Cobotics application
Kemppi Cobotics application is used for configuring DCM network settings and for viewing the communication between
the robot and the welding system. 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 page3.)
1. Scan the QR code below or search for 'Kemppi Cobotics' in Google's Play Store.
2. Install the application.
3. Open the application.
