Failsafe high-end controller
By Mary Del
Oct. 3, 2014 – The Siemens Industry Automation Division has expanded its Simatic S7-1500 generation of controllers with what it calls the most powerful failsafe CPU so far — the Simatic S7-1518F. The new failsafe CPU is suitable for high-end standard and safety-related applications in machine and plant automation. It features a 10-megabyte user memory and has four communication interfaces: a Profinet interface with a two-port switch for communication with the field level; two Profinet interfaces; and one Profibus interface. The high performance and large memory allow connection of up to 128 drive axes and their isochronous operation in the range of 250 microseconds.
