It carries cULus, FM, and CE approvals, making it a fit for machinery shipped to North America or the EU. Power supply tolerance is 20.4 to 28.8 V DC; stay within that window to avoid dropout. ## Communications and I/O Onboard fieldbus includes PROFIBUS DP, Modbus TCP, UDP, and AS-Interface. It can act as both Modbus client and server, with TCP/IP and autocrossing enabled by default. Input and output process-image sizes are 1 024 byte each. ## Programming and memory Programmed in LAD, FBD, or SCL. Integrated memory is 1 Mbyte; program size is limited only by available RAM for code (no expansion slot). Backup time is 480 hours typical, enough to retain user program and data over a long weekend power loss. The CPU is not expandable via memory cards, but the fixed capacity covers mid-size projects.","metaTitle":"Siemens 6AG1211-1AE31-2XB0 SIPLUS CPU, -40°C to 70°C","metaDescription":"SIPLUS S7-1200 CPU for -40 to 70 °C ambient.
