1. A method for use in a wireless system comprising a control node and at least one field-level device, wherein the method comprises:
monitoring a time for a control loop performed on a recurring basis, the control loop involving wireless communication between the control node and the at least one field level device; and
adjusting an intentional delay inserted into the control loop, to regulate the time for the control loop according to a required time, wherein adjusting the intentional delay comprises adjusting the intentional delay to a higher value responsive to the time for the control loop being lower than the required time and adjusting the intentional delay to a lower value responsive to the time for the control loop being higher than the required time.
