MVI56E-MNETCR ♦ ControlLogix Platform
Modbus TCP/IP Multi-Client Enhanced Communications Module for Remote Chassis
Adjusting the Input and Output Array Sizes
Note: It is unnecessary to manually edit the ReadData and WriteData user-defined data types in
the ladder logic, as these are automatically updated to match the changed array sizes from ProSoft
Configuration Builder.
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.
The MVI56E-MNETCR Add-On Instruction rung is configured for 600 registers of
Read Data and 600 registers of Write Data, which is sufficient for most
applications. However, you can configure the sizes of these data areas to meet
the needs of your application.
1 In ProSoft Configuration Builder, expand the Module icon in the tree view and
double-click M
C to contain the number of words for your Read Data area.
OUNT
Important: Because the module pages data in blocks of 40 registers at a time, you should
configure your user data areas in multiples of 40 registers.
