Abstract
A computer implemented method for providing a time slot allocation in a wireless communication schedule for monitoring and control of a control loop in an industrial process, the industrial process having at least one control task and a plurality of wirelessly enabled field devices. The method includes importing dependency information between at least two field devices of at least one control loop, automatically converting the dependency information into a communication schedule and allocating time slots in the communication schedule to one or more field devices of the at least one control loop dependent at least on a dependency relationship between at least two field devices. A system and a computer program product are also disclosed.
