A standard S7-300 central processing unit with MPI, integrated 24 V DC power supply and 128 KB work memory.
6ES7314-1AG14-0AB0 is a SIMATIC S7-300 CPU 314 for established machine and process-control systems. Siemens specifies an MPI interface, integrated 24 V DC supply, 128 KB work memory and a required SIMATIC Micro Memory Card. Replacement planning should preserve the STEP 7 hardware configuration, MPI addressing and memory-card contents before the installed CPU is removed.
