Features

  • 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
