Safety controls- SafeLogic

Published on : Tuesday 30-11--0001

Description

SafeLogic is the high-performance, freely programmable safety control for certified solutions in accordance with IEC 61508 up to SIL3, EN 62061 up to SILCL3, and EN ISO 13849-1 up to Cat. 4 and PL e. It is especially well suited to complex machines and large-scale systems with a decentralized distributed periphery. In terms of hardware, SafeLogic upgrades the standard CML control components through the addition of a function module. This enables the non-safe and safe application to be centrally processed using only one control system.

Standard and safety peripherals such as input/output modules and drives are uniformly linked to the control system via the identical communications interfaces. Safety programming is uniformly carried out using IndraWorks in accordance with the PLCopen Safety standard. In combination with the Sercos automation bus, the CIP Safety on Sercos safety protocol, and the IndraDrive range of drives incorporating SafeMotion, the simple interaction takes place in the form of certified, complete Motion Control solutions.

• Economic solution for machines with a broad range of functions or plant with widely distributed safety peripherals
• Consistent and side-effect-free engineering of standard and safety applications with IndraWorks
• Multi-Master support CIP Safety on Sercos and PROFIsafe
• Seamless, complete Motion Logic solution incorporating IndraDrive with SafeMotion
