MVI56E-MCMR Prosoft ControlLogix Enhanced Modbus

With the reduced data block, the MVI56E-MCMR requires less backplane/network bandwidth and enables simpler scheduling and transfer over ControlNet networks. Additionally, the reduced data block is practically used in remote chassis installation when used with ControlNet communication adapters and redundant controllers.

To install the Prosoft MVI56E-MCMR module, users must have an Allen-Bradley ControlLogix processor with one free slot in the rack for this Modbus module and 800 mA of power available with a 5 Volts DC backplane power source. The device also needs an additional 3 mA from a 24 Volts DC power source. This enhanced Modbus master/slave communication module can be stored at a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit), but it can be used only at a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). For data transfers between the MVI56E-MCMR and processor, sample ladder instructions or add-on instructions are used. On the upper front side of the device, there is a scrolling LED display with 4 characters for status and diagnostic messages display in plain English. This module has a CF card option to store all the user’s configuration settings. In this way, users can replace a defective module with a new one and perform a quick in-the-field transfer all the settings and data from the CF card.
