Product details

What this CPU is

The 6AG1516-3AN00-7AB0: DCP (Discovery and Configuration Protocol) is included — that's the service PROFINET controllers use to identify and assign IP addresses to devices on the wire. FBD is also on board if you program in function block diagrams.

Dimensions match standard version: 105 x 147 x 129 mm. Temperature range extends from -40 to 70°C.

Dimensions 105 x 147 x 129 mm. Supports -40 to 70°C and MRP ring topologies. Up to eight communication modules (CM/CP) can be plugged in for PROFIBUS, additional Ethernet, or serial extensions — the CPU front doesn't block the adjacent slots. Process image is 32 kbyte each for inputs and outputs, adequate for several hundred I/O points within one cycle.

Frequently asked questions

What is the FBD support?

FBD (Function Block Diagram) programming language is supported on this CPU, along with LAD, SCL, STL, and GRAPH.

How many devices can be in an MRP ring with this CPU as redundancy manager?

Up to 50 devices in the ring when using MRP. The CPU can act as the redundancy manager or a client.
