Three integrated Ethernet ports make the modular, compact fail-safe controller suited for stand-alone process applications. Simatic, which can be expanded with a maximum of 64 ET200SP I/O modules, also handles standard and fail-safe distributed applications requiring fast, downstream, local and discrete control for up to 128 I/O devices. System diagnostic information is displayed uniformly and in plain text in the TIA Portal, HMI and web server; and drives are connected via ProfiNet, ProfiBus or analog interfaces.
