Fieldbus Technology: Simplifying Your Automation Tasks

Fieldbus technology combines your valve stacks.

In fact, Fieldbuses are able to connect multiple valve stacks onto one ethernet cable. This means you don’t need to have each of your valve stacks connected individually to a PLC. In fact, each valve stack connects to the main Fieldbus which connects straight into your Ethernet, then onto the PLC.

What Industries Can Use This Technology?

Anyone who uses pneumatics in an automation process is a great candidate to use a Fieldbus. In order to truly determine if a Fieldbus is the right fit for your company, you will need to evaluate the advantages and disadvantages of this technology.

Benefits To Using A Fieldbus

  • Wiring is much simpler and easy as all valve wiring goes straight to the Fieldbus.
  • You can connect a variety of products to a Fieldbus. There is no need to use products from one single manufacturer for a simple connection.
  • Finally, Fieldbuses support many protocols.

Cost To Using One

  • Fieldbuses are not necessarily defined as traditionally cheap equipment. Generally, you will want to decide if it is more cost-effective to have someone manually wiring valves or to use a Fieldbus. If you are paying someone several hours of labor, a Fieldbus is likely a better fit.
  • Training may be necessary to use the Fieldbus hardware.
