The present invention relates to a resource module (38, 40, 42), a resource platform comprising a resource module, an application resource system comprising a resource platform, a process control system comprising an application resource system, a computer program product containing program code for realizing a resource module and a method of isolating a resource from an application. The resource is associated with one of the resource types and comprises said resource module as well as a physical resource (32) and/or an interface to the physical resource (30), at least one action handler for handling a specific action to be performed, by the application, on or for the physical resource and a registrator for registering itself and associated actions handlers (f1, f2, f3) in a register (46) associated with the application, so that the aplication can call an action handler in the resource module for performing an action specialized for the resource type on or for a physical resource.
