Computer-implemented method and system for automatic generation of time slot allocation for a wireless control loop
First Claim
1. 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, said industrial process having at least one control task and a plurality of wirelessly enabled field devices;
- characterized byimporting dependency information between a plurality of said field devices of at least one control loop from any of a computer aided design file, a process and instrumentation diagram in electronic file form, a process logic diagram in electronic file form, a process and instrumentation diagram in the form of an extended extensible markup language file, a process graphic, a controller configuration in a control system, andallocating time slots in said communication schedule to at least one of said field devices of the at least one control loop dependent at least on a dependency information between the plurality of said field deviceswherein said dependency information indicates whether a control task requires as an input an output of one of said field devices or control loops.

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.
