RIO Modular Field Bus System
Field Bus Is Standard
Periphery connection via field bus has largely superseded
conventional parallel cabling for automation – distributed
I/O circuitry offers considerable advantages. The field
devices, sensors and actuators are wired locally to I/O
modules. The signals are forwarded to the controller by the
field bus. Long, expensive and confusing cable routes are a
thing of the past. Segmentation into individual bus nodes
makes it much easier to install and diagnose the system.
The Schleicher RIO (Remote Input Output) system offers a
cutting-edge concept for communication between controller
and periphery. Modular I/O nodes are installed on the plant
floor and networked via the field bus. If required, data (pre-
)processing can be carried out directly in the bus node by
microLine modules with PLC capabilities and function
modules. This reduces the load on the field bus and the
higher-level controller.
Modular
Modules form the interface between PLC/CNC or bus
coupler and the field. With modules you can adapt flexibly
to different tasks and requirements.
• Digital and analog inputs/outputs can be combined as
required. The process-specific signal mix is taken up,
passed on and output, all according to requirements.
• Modules can be changed quickly and simply.
• Sensors and actuators can be wired independently of the
field bus.
• You can change to a different field bus system by just
changing the bus coupler.

Remote
Remote on-the-spot connection instead of wiring in the
central enclosure has decisive advantages.
• Wiring costs are reduced because cable routes are not
required.
• Clarity is increased and maintenance is easier.
• Segmented start-up of plant and machine components is
possible.
• Doing without large central units reduces costs.
Networked
RIO is a consistent complete system for various field bus
systems for machine-building and plant engineering.
• Profibus-DP
Communication with remote periphery devices
• Interbus
Field bus for the sensor/actuator level
• DeviceNet
Simple device network with CAN technology
• CANopen
Real-time-capable multi-master network
Intelligent
RIO allows networked automation to use the enormous
rationalization potential of remote intelligence.
• The microLine PLC controller and the RIO function
modules provide optimally matched controller
performance.
• Local data processing results in short reaction times
without field bus delay and thus increases precision and
reproducibility of results.
• Parallel data processing
reduces bus load.
• Intelligent components
improve emergency
running properties if the
field bus fails.
