1.1 What Are Distributed I/O Devices?
Distributed I/O Device – Area of Application
When a system is set up, the inputs and outputs to and from the process are often
located centrally in the programmable controller.
If there are inputs and outputs at considerable distances from the programmable
controller, there may be long runs of cabling which are not easy to follow, and
electromagnetic interference may impair reliability.
Distributed I/O devices are the ideal solution for such systems:
S The controller CPU is located centrally.
S The I/O devices (inputs and outputs) operate locally on a distributed basis.
S The high-performance PROFIBUS-DP ensures with its high baud rates that the
controller CPU and I/O devices communicate smoothly.
