Black Channel for Safety-relevant data
VARAN provides the possibility to transmit Safety-oriented data using the Black Channel principle. The bus system is thereby excluded from the Safety assessment and allows Safety data to be forwarded over other transport media. For example, an STO signal can be integrated via the VARAN bus system or external backplane wiring.
In systems with multi-manager networks, the Safety signals can be transmitted over multiple machines and are then available to the entire production line.
Central and decentralized Safety solutions up to SIL3 in compliance with IEC 62061 and PLe according to EN ISO 13849-1/-2 can be easily and inexpensively implemented with VARAN.
