Device Net
DeviceNet is another widely accepted open network type with a large variety of third party products.This network type is particularly popular in North America.
DeviceNet is based on a product/consumer operation where peer-to-peer or master/slave configuration are possible. DeviceNet is based on CAN (Controller Area Network) serial bus system. DeviceNet is a cost-effective solution for network integration of low level terminal equipment.
Highlights:
Widely supported by many manufacturers
Up to 500kbps transmission speed
Wide range of Mitsubishi DeviceNet products
Particularly popular in North America

Communication is the key
Profibus offers users the option to mix devices from different companies. It is an open network ranging from simple I/O stations through to complex PLCs.The network allows extremely fast data exchange with a wide variety of slave devices.
The GX Configurator DP software and the profibus master modules combine to give a user-friendly plug and play technology.The configuration software is self-explanatory, using a graphical method to set up the network.You simply select the slave unit, assign the station number and specify where in the PLC the information is stored. As this is an open network, Mitsubishi Profibus units can also be connected to master and slave devices from other manufacturers.
Highlights:
Widely supported by many manufacturers
Up to 12Mbps transmission speed
Easy set-up with GX Configurator DP
Full range of Mitsubishi Profibus products

The High Speed Motion Network
SSCNET (Servo System Controller Network) is Mitsubishi Electric's dedicated Motion Control bus network. The motion controllers and servo amplifiers can be linked via the SSCNET network that offers the user: ease of connectivity, due to less wiring, high reliablilty and since the encoder output terminals are fitted as standard, greater flexibility for system integration.
During operation, all parameters and operational data are available back at the main controller due to the communication provided by the SSCNET system bus.
Highlights:
Synchronous high-speed network especially for motion control bus
Plug-and-play configuration
Bidirectional communication between controller and servo
controller/axis controller
Configuration and diagnostics messages via network
Top-level performance
Serial data transfers
Up to 96 axes simultaneously
Bus cycle time just 0.8ms
