Product details

What fits in the cabinet

The 6AG1511-1AK00-7AB0: Mounts on standard DIN rail. Dimensions: 70 mm wide, 147 mm tall, 129 mm deep. The backup time is 6 weeks at 40 °C ambient – typical for a healthy retentive memory, no battery change anxiety during a shutdown window. Process image handles 32 kbyte each for inputs and outputs, enough for a mid-size station without a remote rack. If you need more than four communication modules (PROFIBUS, PROFINET, Ethernet) you're looking at a bigger CPU.

Programming and connectivity notes

You can program in LAD, FBD, SCL, STL, and GRAPH – no translator needed if your team uses mixed languages. Built-in MODBUS TCP lets it talk to third-party drives or sensors without an extra module. MRP redundancy manager is enabled out of the box; set the ring topology and it handles the switchover. Note: DHCP is not supported (no DIP to enable it), so keep addressing via DCP or LLDP. The web server serves both standard and custom pages – handy for a quick health check from a phone on the floor.

Frequently asked questions

Can this CPU act as an MRP redundancy manager?

Yes, it supports MRP as both redundancy manager and client, with a maximum of 50 devices in the ring.

What is the process image size?

32 kbyte each for inputs and outputs, all in the process image.

Does it have a web server?

Yes, with both standard and user-defined pages over HTTP and HTTPS.
