Prosoft MVI69-ADM

The Prosoft MVI69-ADM is particularly useful in the ControlLogix rack. Its appearance is identical to that of ordinary I/O modules and can be directly inserted into the backplane to convert the CPU's data into serial port signals. The entire process does not require any modification to the original wiring. As a supplier, we provide high-quality products to enable you to upgrade the core system without replacing all components and safely collect data from the old equipment..

Performance

The Prosoft MVI69-ADM has excellent performance. Even when multiple high-baud-rate Modbus RTU devices are connected simultaneously, it can organize the data in an orderly and sequential manner without any congestion or packet loss. Its response delay is extremely low. When the main CPU issues a read instruction and returns the data through the serial port, the entire process is very fast. For those interlock protection signals that require high real-time performance, it can also keep up perfectly. Its anti-interference performance is a major highlight. In many field application scenarios, the interference of the frequency converter is particularly severe. Ordinary serial port conversion devices often report errors frequently. However, this module can reliably extract valid signals and has a complete error frame retransmission mechanism, thus ensuring the accuracy of data acquisition.

Structure

The Prosoft MVI69-ADM chip operates independently and does not consume the computing power of the main CPU of the rack. The chip is surrounded by a complete backplane bus interface circuit, which is used for high-speed data exchange with the rack. On the other side, there is a highly isolated serial communication circuit. This design is very reasonable because industrial site serial cables are usually very long and are prone to lightning strikes or grounding loop interference. It can block all high-voltage interference and ensure the absolute safety of the core control system on the backplane.

Application scenario

This Prosoft MVI69-ADM model is widely used in industrial sites. The most typical example is the renovation of old water plants or sewage pumping stations. The main control has been replaced with the latest ControlLogix, but the flow meters and level meters on site are all old-fashioned Modbus serial port instruments. By simply plugging them into the rack, all the data can be collected. There are also distribution rooms in power systems, where the serial data from numerous microcomputer protection devices need to be centralized and transmitted to the central control room. And in the cement factory, paper factory those harsh environment places, using it to communicate with the remote inverter serial port, not only can save the trouble of long distance drawing analog line, but also can ensure that the signal is not distorted.
