It is thus possible to alert plant operators sooner.

A process display transmits the PMI360D-F130 signals to the plant driver.

The machine operator lost a considerable amount of weight and his blood pressure decreased.

The plant operator can draw conclusions from that information and determine what needs to be changed in the process.

Advantage for the operator: The pipe can be gauged at the tool, immediately.

If alarms follow operator actions, then this can indicate an error by the installation operator.

In case of interruptions of operation the installation operator immediately gets the necessary assistance in order to achieve downtimes as short as possible.

The line operator is able to analyze defect trends and adjust production parameters accordingly.

The encasing plant is operated centrally from a main control panel 26, which is arranged right next to the pipe-welding equipment 27, in order to make it easier for the plant operator to observe the welding process.

Therefore, in practice, a system operator must often intervene in the process, because, based on his experience, he will be able to recognize process states where the desired process behavior is not guaranteed by the conventional automatic control.

Nonetheless, operators often cannot carry out necessary changes in the use of chemicals in a timely manner due to the long downtime with bleaching.

Precognize provides SAMSON with the most sophisticated and advanced process monitoring tool to detect system abnormalities in advance, enabling the operator to take the right action to counteract system failures.

ABB’s solution was retrofitted to enable facility managers to collect data on plant performance and monitor energy efficiency and costs online.

Continuously running online algorithms support the system operator by detecting and correspondingly highlighting deviations from the historically observed signal patterns.

In addition, an operator (plant manager) can in this way easily detect the effects which changes in a parameter have on the calculated set points of the other parameters.

Thus, the method according to various embodiments can not only “suggest” optimized set points, which can, for example, be confirmed by a plant manager or merely accepted as a trend, but can also be used directly as a “control method” with regard to the calculated set points.

In a further embodiment, plant limits or parameter value limits are generated from calculated variables or variables derived from the online model and/or are fixedly predefined and/or predefined by the plant manager and taken into account when calculating a set point.

However, the disadvantage of conventional automation systems and means for maintaining and programming these automation systems is often that, for example, conventional operating and observation systems (HMI systems) usually have access only to a restricted range of the control and process variables handled or processed by the automation units, i.e., only the operating data relevant to the respective plant operator (i.e., operating personnel associated with the operator of the respective technical process).

For example, the normal operation of the system, this degree of opening, which can be always the same, can be irrelevant. However, if the valve opens due to extraordinary circumstances, this can be important information that should be explicitly represented to the system operator.

However, if such a signal changes, this fact can be of importance to the system operator in many cases.

System operators can be relieved of tedious tasks such as judging whether a signal is still silent or is still similar enough in comparison to other signals.

Such a setpoint value adaptation within the filter may be performed manually by the plant operator, or be performed independently by the control.

An open-loop control and/or closed-loop control with said filter that is particularly advantageous according to the development may comprise a signal output, which makes the plant operator aware of the change.

In addition or as an alternative, the advantageous open-loop control and/or closed-loop control with said filter may comprise a value output, which suggests a new setpoint value to the plant operator.

In the normal case, a plant operator may only activate the preferred master control circuit concerning the cooling capacity when he has completed the setting of the sections.

The adjustment of the mixing ratio of the ethene tetramers (4C2) to the butene dimers (2C4) within the olefin mixture to be hydroformylated C8 is effected manually by the plant operator in the simplest case, and ideally in an automated manner by means of standard closed-loop control technology.

Since interactions between the control loops, which in this disclosure are also referred to as cross-influences, couplings or interaction effects, do not generally represent a problem in the operation of a system, they are not in most instances more closely scrutinized by plant operators and are not included in the monitoring of control loops operation.

If one of the process and/or system values is subject to periodic fluctuations, this means that their representation will show corresponding variability. However, fluctuations are often not recognized as such by the system operator and are therefore often interpreted as misalignment.
