Abstract
A wireless network managing device for a wireless network that is part of a process control system. The wireless network managing device includes a node determination element configured to receive an operator selection of at least one node in the process control system via an operator terminal and determine a field device implementing the functionality of the node, and a bandwidth control element configured to adjust a bandwidth assigned to the at least one field device in an auxiliary data section of a communication structure used by the wireless network based on the received operator selection in order to increase system responsiveness.
