Product Description

CPU 314 6ES7314-1AG14-0AB0 PLC Controllers S7-300 Central Processing Unit

Application

The CPU 314 is the CPU for installations with high requirements in terms of processing power and reaction time. With its working memory this CPU is also suitable for medium-sized applications.

Function

Password protection;
a password concept protects the user program from unauthorized access.
Block encryption;
the functions (FCs) and function blocks (FBs) can be stored in the CPU in encrypted form by means of S7-Block Privacy to protect the know-how of the application.
Diagnostics buffer;
the last 500 error and interrupt events are stored in a buffer for diagnostic purposes, of which 100 are stored retentively.
Maintenance-free data backup;
the CPU automatically saves all data (up to 64 KB) in case of a power failure so that the data are available again unchanged when the power returns.
