Physical Connection

  1. 1

    Locate the press controller

    Find the hydraulic press controller panel. Most modern hydraulic presses use a PLC or dedicated controller (Bosch Rexroth, Parker, Moog) with an Ethernet or serial port.

  2. 2

    Connect Ethernet or RS-485

    For Modbus TCP: Cat6 from the controller Ethernet port to the Flowstate edge node. For Modbus RTU: wire RS-485 A/B from the controller serial port to a USB-to-RS485 adapter on the edge node.

    If the press has no controller with a data interface, use a CT101 current clamp on the hydraulic pump motor and a pressure transducer with 4-20mA output.

  3. 3

    Set controller IP (Modbus TCP)

    On the press controller HMI or via configuration software, set a static IP in the 10.0.100.x range. Default Modbus TCP port is 502.

Machine Configuration

  1. 1

    Identify Modbus register map

    Obtain the press controller's Modbus register map from the manufacturer. Key registers: hydraulic pressure (PSI/bar), ram position (mm), cycle count, pump motor current (A), oil temperature (C), and press state.

  2. 2

    Configure Flowstate polling

    On the Flowstate edge node, configure a Modbus TCP/RTU poll with the register addresses, data types, and scaling factors from the register map. Typical poll rate: 500ms for pressure, 1s for temperature.

Verification

  1. 1

    Read pressure register

    With the press idle, read the hydraulic pressure register. Value should be near 0 PSI. Activate the press and verify pressure rises to the set tonnage.

  2. 2

    Dashboard check

    Press appears in Flowstate with hydraulic pressure, ram position, cycle count, and oil temperature.
