Engineers have to physically travel to the actuator, interrogate the controller with a hand held devise or visual check. This is time taking and costly.
With FieldQ with Foundation Fieldbus diagnostics in the control module, the central control room can monitor module health by way of temperature, number of cycles, time of stroke, etc. which can pre-empt any changes in the set up and therefore plan for predictive maintenance without the need for physical site visits.
