What this CPU brings to a panel
The 6AG1515-2FM02-2AB0: On the network side, it handles MRP Automanager per IEC 62439-2 Edition 2.0, managing up to 50 devices per ring for media redundancy. That means a cable break doesn't take the line down—the ring heals in under 200 ms (typical). PROFIsafe is baked in, and the CPU supports failsafe logic in both LAD and FBD—so you can integrate safety functions without a separate safety PLC, as long as the I/O and drive end agree. MODBUS TCP is on the table via the onboard port, useful when tying into older meters or third-party drives. DCP is enabled, making PROFINET commissioning straightforward—plug it in, let the controller assign the name. The process image is 32 kbyte each for inputs and outputs, enough for a medium-sized machine with distributed I/O.
