About the Siemens 6ES7414-2XK05-0AB0

The Siemens 6ES7414-2XK05-0AB0 is the CPU 414-2 of the S7-400. Siemens's data sheet gives it 1 MB of work memory, split into 0.5 MB for code and 0.5 MB for data, a combined MPI/PROFIBUS DP interface at 12 Mbit/s and a second PROFIBUS DP interface. It is powered from the S7-400 rack's system power supply.

What is the 6ES7414-2XK05-0AB0 used for?

It runs mid-sized S7-400 stations with I/O in the rack and distributed I/O on two PROFIBUS DP lines, common in production lines and plant sections built on PROFIBUS.

Lifecycle and successor

Discontinued.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the full order number and the firmware version on the CPU's front label; send a photo of it. S7-400 CPUs of the same type differ by order number in memory and interfaces, so quote against the exact number, and list any interface modules (IF) fitted.
