Product information
Overview
Key Features
- Central processing unit: CPU 317-2 PN/DP for SIMATIC S7-300, with 1 MB integrated work memory and no work-memory expansion.
- Communication interfaces: The first interface is combined MPI/PROFIBUS DP with a maximum transmission rate of 12 Mbit/s. The second is PROFINET with 2 RJ45 switch ports.
- Supply voltage: Rated supply voltage: 24 V DC; permissible range: 20.4 V to 28.8 V DC.
- PROFINET and PROFIBUS functions: Supports PROFINET IO Controller and IO Device functionality, PROFIBUS DP master and device functionality, PROFINET CBA, and Open IE communication via TCP/IP, ISO on TCP, and UDP.
- Processing performance: Typical CPU processing times are 0.025 μs for bit operations, 0.03 μs for word operations, 0.04 μs for fixed-point arithmetic, and 0.16 μs for floating-point arithmetic.
- Configuration and protection: STEP 7 V5.5 or higher is supported. LAD, FBD, STL, SCL, CFC, GRAPH, and HiGraph® programming languages are supported, with user-program/password protection and block encryption.
