4 Click [+] to expand the .CONFIG.M OD D EF
section, and then change the
R EAD R EG C NT
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.
