Product details

Extended-temperature PROFINET controller

The 6AG1511-1AK01-7AB0: On the network side it carries PROFINET IRT with MRPD, enabling isochronous motion on the same cable as standard IO and MRP ring redundancy — critical for drive lines and high-availability plant networks. It acts as an MRP redundancy manager or client, supporting up to 50 devices in the ring. Process image is 32 kbyte for both inputs and outputs — enough headroom for a medium-sized distributed rack with analog and digital signals. The CPU also integrates a PID controller with auto-tuning for temperature and a three-step PID for valves, plus a web server with editable pages for diagnostics via HTTPS or HTTP. MODBUS TCP and UDP are built in; additional communication modules (CM/CP) are limited to four. Programming languages supported include LAD, FBD, STL, SCL, and GRAPH — no difference from the standard CPU on that front. The hardware clock is battery-backed.

Frequently asked questions

What is the listed DCP (Yes) on this component line?

The discovery and configuration protocol (DCP) is supported, enabling network assignment of IP address and device name over PROFINET.

What is the listed FBD (Yes) on this component line?

Function block diagram (FBD) is one of the programming languages available on this CPU.

Does 6AG1511-1AK01-7AB0 drop into a panel specified for 6AG1511-1AK00-7AB0 without rewiring?

Yes — the -AK01 is the direct successor to the -AK00; both share the same 70 × 147 × 129 mm housing, same backplane connector, and same terminal assignments. No wiring changes are needed.
