CPU 315-2 DP for S7-300 Rack
The Siemens 6ES7315-2AF83-0AB0 is a CPU 315-2 DP module for the S7-300 series, designed to snap onto a standard DIN rail inside a control panel. It draws 24 VDC rated supply and dissipates 8 W typical power loss, so budget for that heat load in the enclosure ventilation. This CPU supports programming in LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC, and includes an integrated MPI interface plus PROFIBUS DP slave capability. The 80 mm width, 125 mm height, and 130 mm depth fit the standard S7-300 slot footprint.
Panel Fit and I/O Map
The CPU provides 244 bytes each of inputs and outputs, with 128 digital channels central and up to 256 bytes of process image size. The 1 ms to 6000 ms cycle time range is adjustable, with equidistance supported for deterministic PROFIBUS DP cycles.
