Application :
• It is used in plants containing distributed automation structures in addition to a centralized I/O.
• It can be implemented as a PROFINET IO controller and as a standard PROFIBUS DP master in the SIMATIC S7-300.
• The 315-2 PN/DP CPU can also be used as distributed intelligence (PROFIBUS DP slave or PROFINET I-Device).
• Motion control with Easy Motion Control.
• Implementation of control engineering tasks using STEP 7 blocks or runtime software Standard PID Control/Modular PID Control.
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.
• Maintenance-free data backup;
the CPU automatically saves all data (up to 128 KB) in case of a power failure so that the data are available again unchanged when the power returns.
