- Master or Slave Devices Available (see details below)
- Fully Integrated into Epson RC+ Development Environment
Fieldbus I/O is used in factories worldwide to reduce cabling costs, setup time, and promote standard device usage. However, there is not 1 accepted Fieldbus I/O standard. Instead there are quite a few different ones. The more commonly used Fieldbus I/O standards are: DeviceNet, Profibus, ProfiNet, EtherNet/IP, EtherCAT, and CC-Link.
Some of the more common reasons factories use fieldbus I/O as opposed to normal discrete I/O solutions are shown below:
- Access to signals from multiple devices and multiple data from each device using one cable
- Precise signal transmission since there is no need for A/D conversion and D/A conversion.
- Less wiring costs, including signal relay board costs and installation area due to several dozen (or a hundred) devices connected on one fieldbus
- More flexible modification and expansion of a system because multiple devices are simply added to one Fieldbus without additional wiring
