The achievable Safety Integrity Level SIL3 complies with IEC 61508 2nd Edition / PL e (Performance Level) to ISO 13849. The new Simatic S7 1214FC and S7 1215FC controllers and corresponding failsafe I/O modules offer compact, powerful and cost effective failsafe control. The scalable controllers provide fast throughput with easily reproduced control cabinets. The controllers' TÜV-certified Failsafe-library handles all conventional safety functions. Enhanced standard and safety diagnostics reduce downtime. Safety relevant documentation is provided with a standard-compliant Failsafe-Program printout. Both failsafe controllers are DC/DC/DC or DC/DC/Rly variant. They include 24 integrated standard inputs/outputs and an integrated Ethernet interface. Expandable up to eight standard or fail-safe signal modules, the controllers feature one signal board, up to three communication modules (CM), two integrated 0 to 10 V standard analog inputs and two 0 to 20 mA analog outputs. The TIA Portal option package Simatic Step 7 Safety Basic V13 SP1 includes many new engineering functions and supports the portfolio of failsafe S7 1200 controllers.
