The openSAFETY network
An openSAFETY network may contain up to 1023 safety domains, with up to 1023 nodes or devices permitted within each of these. Safety domains can extend over different and inhomogeneous networks, and can integrate the safety nodes that are scattered throughout these into one domain. Safe and unsafe devices can be operated within one domain. Gateways allow for intercommunication between different safety domains. openSAFETY enables users to enforce hierarchical separations as well as to establish separate safety zones on a network. Therefore, e.g. installations can be made in one zone, while production in other zones carries on unimpeded. In every domain, a Safety Configuration Manager (SCM) is responsible for continuous monitoring of all safety nodes.
