Prosoft MVI71-ADM

The Prosoft MVI71-ADM can be directly inserted into the 1771 rack and can monitor every data byte on the backplane in real time. This helps you clearly identify those hard-to-detect system states. In China, Tongtu, as a well-established supplier, recommends this latest product that has undergone backplane signal integrity testing and listening function verification. This enables you to no longer be at a loss when dealing with old PLC failures, but to accurately locate the problem and protect the valuable assets of the factory.

Structure

The core of this Prosoft MVI71-ADM is a high-performance microprocessor. This chip not only processes data, but more importantly, it is equipped with special logic that enables it to directly access all the data flow processes on the 1771 backplane bus. The circuit board integrates a high-precision clock circuit, which is used to attach precise timestamps to the captured data, which is crucial for analyzing sporadic faults. At the bottom is the serial port driver circuit section. To prevent external computers from bringing interference back into the rack when connected, optical coupling isolation processing is done here. The overall circuit layout is very compact, which is the classic single-slot module design style. It needs to fit powerful functions into a narrow space while ensuring good heat dissipation, and the design skills are very profound.

Specification

Application scenario

This Prosoft MVI71-ADM is used in an extremely wide range of applications. The most typical example is the pump station renovation in wastewater treatment plants. The main control is done with CompactLogix, and there are dozens of frequency converters and energy meters hanging below, all with Modbus RTU interfaces. By simply plugging it into the rack, all of them can be managed directly. There are also control systems for conveyor lines in the food and beverage industry, used to read data from weighing instruments and inkjet printers. And there are small-scale water conservancy and hydropower projects, used to connect various water level gauges and gate sensors. For any scenarios where a CompactLogix controller is used, multiple serial port devices need to be connected, and there are space requirements, this Prosoft MVI69-MCM is the standard configuration.
