What is the B&R X67BCE321.L12?

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.
