プロソフト MVI46-MBP

Yueyang Tongtu has the Prosoft MVI46-MBP in stock, which can be delivered to customers immediately. It can be directly inserted into the 1771 rack of PLC-5 and act as a universal converter, enabling the original PLC-5 to easily read all data on the Modbus Plus network. This allows for the connection of different protocol devices to the network at the lowest cost without the need to replace the main control CPU.

Our quality

Our Prosoft MVI46-MBP is an original imported product. Many second-hand products on the market have their back pins loosening or turning black due to frequent plugging and unplugging. We offer brand-new genuine products, including the internal battery (if any) and capacitors, to ensure that their parameters meet the standards. We also provide the user manual. You can use it with peace of mind, without worrying about the module malfunctioning after just a few days of use due to hardware aging.

How to maintain

When maintaining this Prosoft MVI46-MBP module, several details need to be noted. Since it operates in the Modbus Plus network environment, the main focus should be on the connection of the "network terminal resistor". If your module is at the head or tail of the network, make sure the terminal resistor is turned on (or externally connected) as failure to do so can lead to unstable communication due to signal reflection. Regularly check the connection terminals to prevent loosening. If you notice the module temperature is too high, check whether the fan in the control cabinet is blocked. This thing is very durable. As long as the power supply is normal and the network connection is correct, it generally doesn't require special maintenance.

Application scenario

This Prosoft MVI46-MBP module is a must-have in certain industries. The most common application is the renovation of mixing stations in the chemical industry. The main control system is the old PLC-5, but the newly added frequency converter uses Modbus Plus, and with it, all the frequency, current, and torque of the frequency converter can be collected. There is also the networking of pump stations in water treatment plants, where the data from the on-site flow meters and energy meters is aggregated through Modbus Plus to the old system in the control room. And in oil and gas pipeline booster stations, it is used to connect various third-party process controllers. For any situation where one does not want to abandon the existing PLC-5 system architecture but must connect Modbus Plus devices, this Prosoft MVI46-MBP is the standard solution.
