The Simatic ET 200SP failsafe controllers are equipped with three integrated Ethernet ports that make them suitable for standalone applications. They can be expanded with a maximum of 64 ET200SP I/O modules. The modular and compact controllers also handle standard and failsafe distributed applications requiring fast, downstream local discrete control for up to 128 I/O devices. They integrate with and offer the same functions as the Simatic S7-1200 and S71500 controllers, including password protection against unauthorized reading out and modification of program blocks. System diagnostic information is displayed uniformly and in plain text in the TIA portal, HMI and web server.
