CPU PLC S7-400
– The power PLC for the mid to high-end performance ranges
– The solution for even the most demanding tasks
– With a comprehensive range of modules and performance-graded CPUs for optimal adaptation to the automation task
– Flexible in use through simple implementation of distributed structures
– User-friendly connections
– Optimal communication and networking options
– User-friendly handling and uncomplicated design without a fan
– Can be expanded without problems when the tasks increase
– Multicomputing: Simultaneous operation of several CPUs in one S7-400 central device. Multicomputing distributes the overall performance of an S7-400. For example, complex tasks in technologies such as open-loop control, computing or communication can be split and assigned to different CPUs. And every CPU can be assigned its own local I/O.
– Modularity: The powerful backplane bus of the S7-400 and the communication interfaces that can be connected direct to the CPU enable high-performance operation of a host of communication lines. This permits, for example, the division into one communications line for HMI and programming tasks, one line for high-performance and equidistant motion control components, and one “normal” I/O fieldbus. Additionally required connections to MES/ERP systems or the Internet can also be implemented.
– Engineering and diagnostics: The S7-400 is configured and programmed extremely efficiently together with the SIMATIC Engineering Tools particularly in the case of extensive automation solutions with a high engineering component. For this purpose, high-level languages such as SCL and graphical engineering tools for sequential control systems, state graphs and technology-oriented diagrams are available, for example.
CPU PLC S7-400H
– Conformal coating (G3) as standard for increased resistance to environmental influences
– High-availability automation system with redundant design
– For applications with high fail-safety requirements: Processes with high restart costs, expensive downtimes, little supervision, and few maintenance options.
– Redundantly designed central functions
– Increases availability of I/O: switched I/O configuration
– Also possible to use I/Os with standard availability: single-sided configuration
– Can be used with versatile, scalable SIMATIC ET 200SP HA I/O system via STEP 7
– Hot standby: Automatic reaction-free failover to the standby unit in the event of a fault
– Configuration with 2 separate or one divided central device
– Connection of switched I/O via redundant PROFIBUS DP or system-redundant PROFINET I/O
CPU PLC S7-400F/FH
– Fail-safe automation system for plants with increased safety requirements
– Complies with safety requirements to SIL 3 in accordance with IEC 61508, AK6 in accordance with DIN V 19250 and Cat. 4 in accordance with EN 954-1
– If required, also fault tolerant through redundant design
– Without additional wiring of the safety-oriented I/O
– Safety-related communication via PROFIBUS DP with PROFIsafe profile
– Based on S7-400H and distributed ET 200 I/O with fail-safe modules
– Standard modules for non-safety-oriented applications can also be used in the automation system
– Isolation module for the combined use of fail-safe and standard modules in safety mode in one ET 200M
