There are many more advanced control algorithms for MVI56-LTQ. At present, many domestic and foreign control software companies and DCS manufacturers are competing to develop engineering software packages for advanced control and optimised control, hoping to embed advanced control and optimised control strategies in the configuration software. When a large amount of field information is directly entered into the computer control system by the intelligent instrument or through the field bus, there exists the problem of sharing and interacting with the field information by the application programme inside the computer.

With the connection standard of MVI56-LTQ, industrial control software often needs to develop special drivers for hardware devices. This requires changes to the corresponding drivers once the hardware devices are upgraded, increasing the maintenance costs of the system. Even if the SCADA in the computer has an independent driver, it is generally not allowed to access the same device at the same time, otherwise it is easy to cause a system crash.

MVI56-LTQ, as the bottom part of the whole information system of the enterprise, will inevitably need to be integrated with the process management and operational decision-making level, so that there is also the problem of how to monitor the computer and other computers to communicate and transfer information. Since the control system is often a special system developed by different manufacturers, poor compatibility with each other, and high-level business management software and the lack of effective communication interface, so the communication specification problem has become a constraint on the control system to break through the “information island” bottleneck.
