1FK6063-6AF71-1EH0 DCS selection process need to pay attention to what
No matter in the new unit or the old unit of the control system transformation, are faced with the problem of choosing the ideal control system as high quality and low cost as possible. Here, we put aside the price of the control system, only from the perspective of improving reliability to consider, the small edition of the instrument world network that the DCS selection process needs to pay attention to the following aspects of the problem:
1, 1FK6063-6AF71-1EH0 in the selection of DCS control system, priority should be given to the control system with good operating performance on similar units, such a control system has passed the factory test and actual operation, and its reliability has been tested by time.
2,1FK6063-6AF71-1EH0 t1FK6063-6AF71-1EH0he hardware of the control system must have high reliability, mature technology is used in the production process of electronic components, and it is best to hot-plug electronic modules. The calculation and storage capacity of the controller should be sufficient, and the IO card has a strong anti-interference ability.
3, the control system from the structure to fully use redundancy technology. The controller and network communication of the control system must be redundant, and the redundant devices must be able to realize undisturbed switching. The use of redundant structure can not only avoid the expansion of local faults of the control system, ensure the safe and stable operation of the unit, but also ensure the online elimination of equipment faults, thus eliminating the hidden dangers of accidents.
4, 1FK6063-6AF71-1EH0the control system software maintainability is better. In particular, the following aspects:
The stability of the program and software is good, and there will be no problems such as system or single controller crash;
The system self-diagnosis is good, the controller and I/O signal have error alarm;
Man-machine exchange friendly, can modify the program online and down;
1FK6063-6AF71-1EH0Spare parts have a reliable guarantee, easy to purchase within 15 years and short cycle, low price;
The readability of the control system software is good, and whether the function of the configuration function block can easily realize the needs of various process functions of the DCS control system.
Through the brief introduction of the above content, I believe that everyone has a certain understanding of the selection of DCS control system. Hope to help you to better use DCS.
