What the ratings mean for the BOM line
The 6AG1513-1AL01-7AB0: Process image: 32 kbyte inputs, 32 kbyte outputs. That wall limits distributed I/O data per cycle; match against your rack and remote drops headroom. Code work memory caps at 300 kbyte – fine for medium machine logic. PROFINET interface supports IRT and MRP (redundancy manager or client, up to 50 ring devices). No DHCP, so fixed IP or DCP assignment is the norm. Web server with HTTPS for standard and user-defined pages – handy for commissioning dashboards but not a safety-level HMI.
