Industrial Ethernet protocols are increasingly
gaining ground for field device
integration in the chemical process industries.
Offering outstanding connectivity, combined
with simple and robust transmission
technologies, these protocols are key enablers
for enhanced data integration, intelligent
analytics and IIoT applications.
AUMA electric actuators support these
standards and can be easily integrated in
Profinet, EtherNet/IP and Modbus TCP environments,
enabling plant managers to fully benefit
from the enormous potential to optimize processes
and maximize plant availability.
With bandwidths up to 100 Mbit/s,
AUMA actuators provide reliable and rapid
exchange of both cyclic process data and
acyclic diagnostic data from the actuators.
The wide range of diagnostic data that is
automatically logged by the actuators is imOptimize
calibrations
Putting data to work by optimizing calibration
intervals
A
chieving the correct balance between too much calibration
and too little is a challenge for anyone reliant on critical measurements.
Many companies follow a static interval approach and
calibrate once a year during scheduled downtimes. This fixed calibration
interval selection is a typical illustration of established but
outdated rules.
Ideally, calibration intervals should be chosen to reflect an acceptable
risk that the measurement error has not drifted outside
of an acceptable range. Considering common practice, this is seldom
the case. Often calibration intervals are set to one year for the
sake of convenience as it aligns well with annual planning cycles.
However, calibration intervals should be optimized to find the best
trade-off between cost and risk.
Using established existing statistical methods as a base,
Endress+Hauser has developed an enhanced method for calibration
interval optimization. With Calibration Interval Optimization
Endress+Hauser has developed a service that delivers more than a
calculated result. Significant interval changes are discussed, and
all underlying assumptions validated together with the customers.
Intervals are then included as one of a number of operational constraints
including downtime availability to deliver a fully optimized
calibration execution schedule. In the end, the customer benefits
from an overall reduction of both cost and risk.
This scientific model has been proven across +22 billion calibrations
and considers past calibration results to predict future behavior
with the following main results:

mediately available at network level and can
be further used for analysis, process visualisation,
or simulation, facilitating conditionbased
predictive maintenance and efficient
asset management.
Providing utmost flexibility, the actuators
can be integrated into line, star and loop
topologies, using different transmission
media such as copper cables, optical fibres
and wireless technologies. AUMA provides
standardised device descriptions as GSDML
or EDS files and Field Device Integration
Packages, thus facilitating device integration.

*
67% of current calibration intervals could be significantly
increased
* only 20% of instruments are set up with an optimal calibration
interval
* time operating out of tolerance can be reduce by 46% compared
to a static approach
Calibration Interval Optimization uses a proven scientific model to
determine intervals between calibrations.
It includes:
* Determination of optimal calibration intervals using innovative
methods
* Consultancy provided by metrology experts
* Alignment to, and application of intervals according to operational
constraints
The benefits:
* Reduction of calibration costs due to extended calibration
intervals
* Reduced out of tolerance risk as calibration intervals are reduced
