What You Need

Cat6 Ethernet cableIncluded in kit
Flowstate CL260 edge nodeIncluded in kit

Customer provides:

  • Network access to robot controller
  • Teach pendant access for configuration

Physical Connection

  1. 1

    Locate the Ethernet port

    On the UR control box, find the RJ45 Ethernet port on the bottom panel.

  2. 2

    Connect Ethernet cable

    Run Cat6 from the control box Ethernet port to the Flowstate edge node.

  3. 3

    Set robot IP

    On the teach pendant: Settings > System > Network. Set a static IP in the 10.0.100.x range, subnet 255.255.255.0.

Machine Configuration

  1. 1

    Enable Remote Control mode

    On the teach pendant: Settings > System > Remote Control. Enable remote control to allow external monitoring and program state queries.

    Remote Control mode does not give external write access unless explicitly configured in the safety settings.

  2. 2

    Enable Modbus TCP server

    The UR e-Series has a built-in Modbus TCP server on port 502 (enabled by default). Verify via Installation > Fieldbus > Modbus.

  3. 3

    Map Modbus registers

    Key registers: 128-133 (joint positions), 139-144 (joint temperatures), 256 (robot mode), 258 (safety status), 260 (program state), 400+ (digital I/O).

Verification

  1. 1

    Read Modbus registers

    From the edge node, read holding register 256 (robot mode). Values: 0=disconnected, 5=idle, 7=running. Non-zero confirms communication.

  2. 2

    Dashboard check

    Robot appears in Flowstate with joint positions, speed, program state, and safety status.
