What the 48 KB working memory means for your program
The Siemens 6ES7315-1AF01-0AB0 is a CPU 315 from the S7-300 family, packing 48 KB of working memory — enough for mid-size machine logic but tight for a full motion-control or batch-sequencing application that also runs a Profibus DP network. If your program footprint is pushing past 40 KB, this CPU leaves almost no headroom for online changes or additional function blocks.
