Description
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.
Application: PLC controller
Used with: SIMATIC S7-400 rack (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.
Key features
- 1 MB work memory: 0.5 MB code, 0.5 MB data
- 1st interface MPI/PROFIBUS DP 12 Mbit/s (X1)
- 2nd interface Ethernet/PROFINET (X5), media redundancy
- Isochronous mode via PROFIBUS DP or PROFINET
- Powered from the S7-400 system power supply
