Description
Description: The ProSoft MVI56-LTQ Limitorque Valve Network Interface Module has 1 Slot(s) and Ladder Logic Data Transfer. The module has a Local or Remote Rack Type and a 1200-38400 Baud Rate.
The MVI56-LTQ is a Limitorque Valve Actuator Master Communication Module manufactured by Prosoft Technology. It is a part of the ControlLogix platform used in industrial automation systems supported by Allen-Bradley control logic. The Prosoft MVI56-LTQ is designed to allow processors that are ControlLogix compatible to communicate in a fast manner with Limitorque Valve Actuators. The best way to describe this device is as an input-output medium between the Limitorque valve network and controlling devices that need to send a large amount of data to these actuators. This device supports 150 valves for the storage and transfer of data from the ControlLogix processor’s controller tags. The data that is distributed from PLC processors is asynchronous from the activities on the actuator network. To be able to transfer data to actuator efficiently, the MVI56-LTQ has 1500-word sized buffer. In this memory, the device can store the ladder logic program that is responsible for the control of actuators in the network. The Prosoft MVI56-LTQ has backplane current load of 800 mA at 5 Volts DC. It can be operated at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) temperatures. It is equipped with 4 LED status indicators that inform the user about module status, backplane transfer status, application status, and serial activity. The module detects hardware problems automatically and turns OK LED on the front of the module to red color. The unit is delivered with RJ45 to DB9M cables for each port and with an RS-232 configuration cable.
The MVI56 Limitorque Valve Actuator Master Communication Module allowsControlLogix compatible processors to interface easily with Limitorque ValveActuators and other Limitorque protocol compatible devices. The MVI56-LTQ module acts as an input/output module between the Limitorquevalve network and the ControlLogix processor. The data transfer from theControlLogix processor is asynchronous from the actions on the network. The1500-word register space in the module transfers the valve information from themodule to the processor. Ladder logic is responsible for control of the valves.Data transferred from the processor to the module instructs the module toexecute commands to valves on the Limitorque network.
