Product Description
Key Features
- SIPLUS S7-300 CPU: CPU 315-2 DP central processing unit based on 6ES7315-2AH14-0AB0, with conformal coating.
- Supply voltage: Rated supply: 24 V DC; permissible range: 19.2 V to 28.8 V. A power supply according to EN 50155 shall be used.
- Memory configuration: Integrated work memory: 256 kbyte, not expandable. Plug-in MMC load memory is supported up to 8 Mbyte.
- MPI and PROFIBUS DP: The unit has an integrated RS 485 interface for MPI and PROFIBUS DP master/slave communication, with transmission rates up to 187.5 kbit/s for MPI and 12 Mbit/s for PROFIBUS DP.
- Processing and capacity: Typical CPU processing times are 0.05 μs for bit operations, 0.09 μs for word operations, 0.12 μs for fixed point arithmetic, and 0.45 μs for floating point arithmetic.
- Lifecycle and environmental variant: Product cancellation is stated. The SIPLUS variant has conformal coating and a -25…+60 °C range.
