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.
