Type SFB, so it handles safety-rated logic over PROFIBUS or PROFINET without a separate safety relay — saves a DIN-rail slot. Programming options include LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC; useful when the integrator defaults to one language but the plant spec requires another. This CPU accepts 244 bytes of inputs and 244 outputs, with 16 overall counters and retentive data that must be restarted at each restart. Width is 40 mm, height 125 mm, depth 130 mm — standard S7-300 clip-fit; leaves room alongside for the power supply and an FM module pair. ## Sourcing & Supply Type SFB fail-safe CPU with PROFIsafe support.","metaTitle":"Siemens 6ES7315-2FJ14-0AB0 CPU 315F-2 PN/DP Fail-safe, FM 8","metaDescription":"Siemens 6ES7315-2FJ14-0AB0 fail-safe CPU for S7-300 with integrated PROFINET IRT.
