The 0.02 A²·s I2t rating on the datasheet is small — it covers the internal electronics, not the power-supply inrush. If you're feeding this from an external 24 VDC, size the breaker for the PS inrush, not this number. ## Networking and redundancy Two-port PROFINET with IRT for isochronous motion control and MRP as redundancy manager or client (up to 50 devices in the ring). Also speaks MODBUS TCP and UDP. DCP for configuration discovery. S7 routing is supported, so a remote engineering station can reach subnets beyond the local PROFINET. ## Programming toolchain Programmable in LAD, FBD, SCL, STL, and GRAPH. FBD and LAD include failsafe blocks — no extra safety license needed. The integrated controller is tuned for valve positioning with optimization.","metaTitle":"Siemens 6AG1511-1FK00-2AB0 SIPLUS S7-1500 CPU, -40 to 70°C","metaDescription":"SIPLUS S7-1500 CPU with -40 to 70°C range.
