The products offered by Rockwell Automation are control systems, industrial control components, information software, motor control devices, sensing devices, network technology, safety technology, and industrial security.
The services offered in Rockwell Automation are repair, asset management consulting, and remote support centers and training.
ABB group, the name itself says. ABB was founded in 1988.

The FY for Rockwell Automation as compared to ABB has seen growth over the period from 2016 to 2019. A clear representation of steady growth with bare minimum fluctuations for each year.

Even though the revenue generated is low as compared to the ABB group. The growth has been magnificently maintained at a proper rate.
In my opinion, the high revenue has been generated by ABB but if you compare the growth rate per year for both companies. Rockwell Automation is a steady bull to bet on.
