Powerful processor: The CPUs achieve instruction execution times as low as 0.03 µs per binary instruction.
CPU 416-2: 8 MB main memory (of which 4 MB each for program and data); CPU 416-3: 16 MB main memory (of which 8 MB each for program and data); CPU 416-3 PN/DP: 16 MB main memory (of which 8 MB each for program and data); fast main memory for parts of the user program relevant to execution.
Flexible expansion: Up to 262144 digital and 16384 analog inputs/outputs.
Multi-point interface MPI: With the MPI it is possible to establish simple networking of max. 32 stations at a data transmission rate of up to 12 Mbps. The CPUs can establish up to 44 connections to stations of the communications bus (C bus) and the MPI.
Mode selector switch: Designed as toggle switch.
Diagnostics buffer: The last 120 fault and interrupt events are retained in a ring buffer for diagnostic purposes. The number of entries can be parameterized.
Real-time clock: The date and time are appended to diagnostic messages of the CPU.
Memory card: For expansion of the integrated load memory. RAM and FEPROM cards (FEPROM for retentive storage) are available.
Combined MPI/DP interface and integrated PROFIBUS DP interface (with CPU 416?2 and CPU 416?3): The PROFIBUS DP master interface allows a distributed automation configuration offering high speed and ease of use. From the user's point of view, the distributed I/O is treated as central I/O (same configuring, addressing and programming). Mixed configuration: SIMATIC S5 and SIMATIC S7 as PROFIBUS master acc. to EN 50170.
CPU 416-3 and CPU 416-3 PN/DP also include:
1 module slot: Using the IF 964-DP interface module, an additional PROFIBUS DP master system can be connected.
