About the Siemens 6ES7412-2EK06-0AB0
The Siemens 6ES7412-2EK06-0AB0 is the CPU 412-2 PN, the entry CPU of the S7-400 with PROFINET. 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 an Ethernet/PROFINET interface. It is powered from the S7-400 rack's system power supply.
What is the 6ES7412-2EK06-0AB0 used for?
It runs S7-400 stations that need PROFINET but not a large program, such as smaller lines and plant sections, with I/O in the rack and on PROFIBUS DP or PROFINET.
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.
Alternatives for 6ES7412-2EK06-0AB0
The manufacturer’s named successor and other parts in the same family. None is a drop-in replacement without checking wiring, I/O and configuration for your installation.
