The 6ES7514-2WN03-0AB0: No IRT on this unit, so skip it for isochronous motion applications. For discrete manufacturing or process lines that need failsafe logic, it's a solid fit. Supports DCP for automatic IP assignment and DNS for hostname resolution — saves a trip to the switch config in a panel swap.

Product details
Frequently asked questions
What does DCP supported mean for this CPU?
DCP (Discovery and Configuration Protocol) is enabled by default (Yes), so the CPU can obtain an IP address automatically from a DCP tool or another device on the network without a DHCP server.
What DNS support does this CPU have?
DNS is supported (Yes), meaning the CPU can resolve hostnames to IP addresses for network communication.
What PROFIsafe version does this CPU support?
It supports PROFIsafe V2.4 and V2.6, so it works with both current and legacy failsafe I/O blocks.
What is the process image size for inputs and outputs?
Both input and output process images are 32 kbyte each, sufficient for moderate I/O counts without expansion modules.
