The Industrial Communications SDK enables real-time industrial communications for TI processors. Industrial communication is typically handled by the Programmable Real-Time Unit Industrial Communication Subsystem (PRU-ICSS). The PRU-ICSS is a co-processor subsystem containing Programmable Real-Time (PRU) cores and Ethernet media access controllers (EMACs), which implement the low level industrial Ethernet and fieldbus protocols through firmware. The upper layers of the protocols stacks are implemented in software running on ARM cores.

PRU cores are primarily used for industrial communication, and can also be used for other applications such as motor control and custom interfaces. The PRU-ICSS frees up the main ARM cores in the device for other functions, such as control and data processing.

Attention: This SDK also includes AM263X MCU+ SDK.
