Abstract: A method in a system is provided for handling failures in a process control system comprising a plurality of compute nodes. The process control system comprises at least two instances of virtualized distributed control nodes, VDCNs, deployed in a respective compute node of a cluster of at least two compute nodes, wherein a first VDCN is a primary VDCN controlling an automated process and at least a second VDCN is a backup VDCN. The method comprises detecting that the number of instances of the VDCNs is less than a set number and assigning the role of primary VDCN to the second VDCN. A device, computer program, computer program product and system are also disclosed.

Abstract: A method for failure detection and role selection for a process in a network of redundant processes including a primary process configured to transmit a heartbeat signal with a predetermined interval to the processes of the network.

Abstract: A method for providing redundancy in a network centric process control system, where at least one node includes at least one control service as well as at least one middleware service for communicating in the process control system, where the control service and middleware service is each a separate executable running in a separate operating system process provided by a real time operating system thereof, wherein a first control service in a first node communicating via a first middleware service and implementing a first control function acts as an active control service for the first control function and a second control service communicating via a second middleware service and implementing the first control function acts as a standby control service for the first control function, the method including performing, by the first control service, the first control function through subscribing, via the first middleware service, to input process data of the first control function and publishing, via the first mid
