Malliga,
Not quite sure what you are asking.
You could poll a work queue for data using the Get Next Item action within the Internal - Work Queues object. Should this return no item, wait for X time and rinse and repeat. Take a look at some of the example processes that Blue Prism supply. Some of the examples include a process that has been designed to poll a work queue.
Note that a robot should never work 24 hours a day. There some be some downtime where the robot virtual machine restarts and any general maintenance can be performed. Also the log files will be massive. Your process can check the current time against a downtime data item and stop processing. Then the schedule will start the process back up.
