parameter from 600 to 1000.

5 To modify the WriteData

array, follow the above steps, substituting WriteData

for ReadData. Also, make sure that the ReadData

and WriteData

arrays do

not overlap in the module memory. For example, if your application requires

2000 words of WriteData starting at register 0, then your Read Register Start

parameter must be set to a value of 2000 or greater in ProSoft Configuration
Builder
.

6 Save and download the sample configuration.

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 in ProSoft Configuration Builder.
