Product details

It runs as an MRP redundancy manager on rings up to 50 nodes and supports IRT for isochronous motion control. Process image holds 32 kbyte each for inputs and outputs, and you can plug up to 8 communication modules (PROFIBUS, PROFINET, Ethernet) into the rack. This CPU does not bring PROFIsafe onboard; safety functions need a separate F-CPU.

Frequently asked questions

What does DCP mean on this CPU?

DCP stands for Discovery and Configuration Protocol. It's supported, so the CPU can automatically detect and assign device names and IP addresses over Ethernet without needing a separate bootstrapping tool.

Does it support FBD programming?

Yes, Function Block Diagram (FBD) is one of the supported programming languages, along with LAD, STL, SCL, and GRAPH.
