Product details

The 6ES7315-1AF03-0AB0: Built-in MPI port handles programming and simple CPU-to-CPU links at 187.5 kbps. For PROFIBUS DP, you use the integrated DP interface. If you need Ethernet, a CP 342-5 occupies one of the two available LAN CP slots; four PtP CPs connect serial devices. The 8 FM-capable slots let you drop in fast counters, stepper modules, or positioning FMs.
