MVI56E-MCM ControlLogix Configuration Communication Module

Description

Make sure your ControlLogix processor and power supply are installed and configured, before installing the MVI56E-MCM module. Refer to your Rockwell Automation product documentation for installation instructions.

Warning: You must follow all safety instructions when installing this or any other electronic devices. Failure to follow safety procedures could result in damage to hardware or data, or even serious injury or death to personnel. Refer to the documentation for each device you plan to connect to verify that suitable safety procedures are in place before installing or servicing the device.

After you have checked the placement of the jumpers, insert the MVI56E-MCM into the ControlLogix chassis. Use the same technique recommended by Rockwell Automation to remove and install ControlLogix modules. You can install or remove ControlLogix system components while chassis power is applied and the system is operating. However, please note the following warning.

In the NEW MODULE dialog box, enter the following values.

The module internal database is divided into two user-configurable areas:

· Read Data

· Write Data.

The Read Data area is moved from the module to the processor, while the Write Data area is moved from the processor to the module. You can configure the start register and size of each area. The size of each area you configure must match the Add-On Instruction controller tag array sizes for the READDATA and WRITEDATA arrays. The MVI56E-MCM sample program is configured for 600 registers of READDATA and 600 registers of WRITEDATA, which is sufficient for most application. This topic describes how to configure user data for applications requiring more than 600 registers of ReadData and WriteData. In this example, we will expand both the Read and Write Data sizes to 1000.
