Join Stacey Jarlsberg, SIMATIC PCS 7 Product Manager, as he explores the physical components that make up the ET 200SP HA high-availability IO system. You will see how easy it is to assemble the IO rail, including connectivity to the redundant PROFINET (R1) network, redundant power, and the new D-SUB terminal block with pre-fab cables to terminal blocks or relays to support 120VAC discrete inputs and outputs.
