    Threads that are spawned from a real-time process, like the SoftLogix controller, execute to the point of blocking, yielding, or Allen-Bradley PLCs completing. The dwell component of the SoftLogix controller allows the continuous task of the controller to give time to other lower priority threads that need to execute.

  • Page 130: Other Nt Considerations

    Windows NT Considerations The following diagram shows the relationship between these objects and shows how one object has to stop running if another with higher priority wants to execute. The SoftLogix controller executes as a real-time priority process, and thus waits for all ISRs and DPCs to complete before executing.

  • Page 131: Running A Softlogix Controller On Windows Nt

    Because SoftLogix runs at a real-time level, it is guaranteed to get as many CPU cycles as it needs before allowing the CPU to execute other application programs. Only DPCs and ISRs run before a SoftLogix controller. Allen-Bradley PLCs Publication 1789-UM002A-EN-P - October 2000...

  • Page 132: Selecting A Dwell Time Setting

    Windows NT Considerations Selecting a dwell time setting Every SoftLogix controller has a main task that can be configured to run continuously or periodically. If set for continuous, the main task would use all of the Windows NT CPU cycles, if it were able, running as a real-time priority process.

    Be careful not to execute too many periodic tasks with short intervals as you can start to use all the bandwidth of the computer without leaving CPU cycles to operate the mouse and keyboard. Allen-Bradley PLCs Publication 1789-UM002A-EN-P - October 2000...

This function lets the controller take care of communication requests that occur from other controllers or from queued requests from within the controller’s application program. The time slice switches the priority level of the continuous task with that of the background communication task, which is always running at a lower level than the continuous task.
