What You Need
Customer provides:
- Press controller register map
- Network or serial access to controller
Physical Connection
- 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.

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.

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