• Fieldbus: PROFINET IO

• I/O configuration via the fieldbus

• Conformance Class B (RT)

• 1 ms minimum cycle time

• Integrated switch for wiring multiple slaves

• 100 Mbit/s full-duplex mode

• Up to 1440 bytes of input data and up to 1440 bytes of output data are possible

• Integrated website

• PROFINET diagnostics and module diagnostics during runtime from within the master environment

• Module and switch diagnostics during runtime using the website or SNMP

• 16 digital channels, configurable as inputs or outputs

• Integrated connection for additional 253 modules via X2X Link

PROFINET (Process Field Network) is an Industrial Ethernet protocol. It uses TCP/IP and is real-time capable.

X67 modules or other modules that are based on X2X Link can be connected to the bus controller. Modular system configurations are optimally supported by PROFINET. Using the device description file (GSDML format), it is very easy to handle project configuration in the respective engineering tool from the manufacturer of the master device.
