Adjusting the Input and Output Array Sizes
The module ’s internal database is divided into two user-configurable areas:
 Read Data
 Write Data
The Read Data is moved from the module to the processor, while the Write Data
is moved from the processor to the module.
The MVI56E-SIE 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.
Important: Because the module pages data in blocks of 200 registers at a time,
you should configure your user data areas in multiples of 200 registers.
Caution: When the array size is changed, RSLogix may reset the SIE tags to
zero. To avoid data loss, be sure to save the settings before continuing.
