Dynamic assigning of bandwidth to field devices in a process control system
First Claim
1. A method for assigning bandwidth to wireless field devices in an auxiliary data section of a communication structure used by a wireless network, where the field devices are assigned a process control bandwidth in a process control data section of the communication structure, said wireless network being provided in a process control system, the method comprising the steps of:
- receiving an operator selection of at least one node in the process control system via an operator terminal, the at least one node being at least one of a plurality of nodes presented to an operator via the operator terminal,determining, via a node determination element of a networking managing device, a field device implementing the functionality of the node selected by the operator, andadjusting the bandwidth assigned to said at least one field device in the auxiliary data section of the communication structure automatically based on the received operator selection by reassigning one or more existing time slots in the auxiliary data section of the communication structure to said at least one field device, where said process control bandwidth is unaffected by the operator selection.

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.

17. A computer program product for a wireless network managing device for a wireless network that is part of a process control system, the computer program product comprising a non-transitory data carrier with computer program code which when run on a processor forming the wireless network managing device, causes the wireless network managing device to:
-
receive an operator selection of at least one node in the process control system via an operator terminal, the at least one node being at least one of a plurality of nodes presented to an operator via the operator terminal, determine, via a node determination element of a networking managing device, at least one field device implementing the functionality of the node selected by the operator, and adjust a bandwidth assigned to said at least one field device in an auxiliary data section of a communication structure used by said wireless network automatically based on the received operator selection by reassigning one or more time slots in the auxiliary data section of the communication structure to said at least one field device, where the field devices are assigned a process control bandwidth in a process control data section of the communication structure, said process control bandwidth being unaffected by the operator selection. - View Dependent Claims (18, 19)
