Adjusting the Input and Output Array Sizes
Tip: If you have not installed ProSoft Configuration Builder, see page 38 for the
steps to install the software.
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-MNETC 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
ODULE
to open an Edit window. Change the R
EAD
R
EGISTER
C
OUNT
to contain the number of words for your Read Data area.
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.
2 To modify the WriteData
array, follow the above steps, substituting WriteData
for ReadData.
