SIMATIC ET 200pro: The Complete Guide to Siemens' Rugged Distributed I/O System
Introduction When automation needs to move out of the control cabinet and onto the machine itself, the hardware must survive conditions that would destroy standard equipment. The SIMATIC ET 200pro is Siemens' answer to this challenge, a fully modular distributed I/O system built from the ground up for direct machine-level installation in harsh industrial environments. With IP65, IP66, and IP67 protection ratings, it eliminates the need for protective enclosures and brings automation intelligence right to the point of action. What Is the SIMATIC ET 200pro?
