The CPU 315-2 DP is a CPU with medium to large program memory and PROFIBUS DP master/slave interface. It is used in installations which have distributed automation structures in addition to a centralized I/O. It is often used as the standard PROFIBUS DP master in SIMATIC S7-300. The CPU is also used as distributed intelligence (DP slave). It has been optimized in terms of its quantitative framework for using SIMATIC Engineering Tools, | CPUs - CPU 315-2 DP CA 01 CPUs - CPU 315-2 DP CPUs - CPU 315-2 DP Overview The CPU with medium to large program memory and quantity framework for the use, if required, of SIMATIC Engineering Tools High processing performance in binary and floating-point arithmetic PROFIBUS DP master/slave interface For extensive I/O configurations For setting up distributed I/O structures Micro memory card required for operation of CPU. Application The CPU 315-2 DP is a CPU with medium to large program memory and PROFIBUS DP master/slave interface. It is used in installations which have distributed automation structures in addition to a centralized I/O. It is often used as the standard PROFIBUS DP master in SIMATIC S7-300. The CPU is also used as distributed intelligence (DP slave). It has been optimized in terms of its quantitative framework for using SIMATIC Engineering Tools, .,: Programming with SCL Sequence control programming with S7-GRAPH In addition, the CPU offers an ideal platform for simple technology tasks implemented in software, .,: Easy Motion Control The solution of closed-loop control tasks with STEP 7 blocks or the runtime software Standard/Modular PID Control Extended process diagnostics can be achieved by using SIMATIC S7-PDIAG. Design The CPU 315-2 DP is equipped with the following: Microprocessor; the processor achieves an execution time of approximately 100 ns per binary instruction and 3 µs per floating-point operation. 128 KB RAM (corresponds to approx. 43 K statements); the extensive RAM for execution-related program sections offers sufficient space for user programs. Micro memory cards (8 MB max.) as load memory for the program also allow the project to be stored in the CPU (complete with symbols and comments) which can be used for data archiving and recipe management.
