Distributed I/O device – Overview
Distributed I/O systems – application area
A plant configuration quite often features a process I/O configuration in a central automation
system.
The wiring of process I/O components installed at a grated distance away from an automation
system may soon may soon become highly complex and susceptible for electromagnetic
interference.
Distributed I/O systems are are the perfect solution for such configurations.
• The controller CPU is located in a central rack.
• The I/O systems (inputs and outputs) are operated locally in a distributed configuration.
What is PROFINET IO?
PROFINET IO is an open transmission system with real-time functionality defined in
accordance with the PROFINET standard. This standard defines a manufacturer-independent
communication, automation and engineering model.
Industrial-strength connections are available for wiring the PROFINET components.
• PROFINET discards the hierarchical PROFIBUS master/slave concept. and deploys a
provider/consumer principle instead. The IO Devices that will be subscribed to by an IO
Controller are defined within the planning phase.
• The quantity structures are extended in accordance with the available quantities for
PROFINET IO. Parameter limits are not exceeded during configuration.
• The transmission rate is 100 Mbps.
• The configuration interface for users is generally the same as that for PROFIBUS DP (the
system is configured in STEP 7 > HW Config).
