Fieldbus Valve Islands for Ethernet and Networked Pneumatic Valves

Fieldbus valve islands connect a bank of pneumatic valves straight to the PLC network, so one cable replaces dozens of coil wires. TSA Hydraulics Engineering supplies them within the Pneumatic Valves family of our Valves range, as complete islands, bus nodes and valve modules.

Swapping a networked island is half hardware and half software. The valves bolt on in minutes, but the PLC still has to recognise the new node, with the right device name, IP address and configuration file. Send us the island series, protocol and node part number, and we will match a genuine unit or an equivalent that talks the same language.

What a Fieldbus Island Adds

A standard island uses one multipin plug. A fieldbus island adds a bus node, which is a small controller on the island that talks to the PLC. That brings:

Fewer cables: one network cable and one power cable for the whole island.
Diagnostics: the PLC can see a broken coil, a short circuit or low voltage.
Local inputs and outputs: modules for sensors, analog signals and extra outputs.
Separate power: valve power can be cut for safety while the network stays live.

Common Protocols

EtherNet/IP: widely used with Rockwell and Allen-Bradley PLCs.
PROFINET: common on Siemens systems.
EtherCAT: for fast, tightly timed motion control.
Modbus TCP: a simple open option on many PLCs.
IO-Link: a point to point link, handy for small islands near the machine.
Older fieldbuses: PROFIBUS, DeviceNet and CANopen are still running on many sites.

The protocol must match your PLC. A PROFINET node will not talk on an EtherNet/IP network.

Replacing a Bus Node or Island

Read the series and the node part number from the label.
Note the protocol, firmware version and network address.
Back up the PLC project and the island’s configuration.
Fit the new node, then load the right configuration file, such as a GSDML, EDS or ESI file.
Set the device name or IP address, then test each valve from the PLC.

Valve modules can usually be swapped without touching the network setup.

Getting Good Results

Use shielded industrial network cable and proper connectors.
Keep network cables away from motor and drive cables.
Fit a separate, switched supply for valve power.
Use the diagnostics in your PLC program, not just the outputs.
