Configuration Data File
The configuration data file is not used. Instead the output data file is used to
configure the module.
Output Data File
The output data file is used to configure the 1762sc-IF4OF4 module. Take care
when making changes to the configuration (i.e. output data file) while in run mode.
Illegal configurations could fault the controller.
The table below shows the layout for the output data file. Note that words 4
through 7 are used to define the module configuration.
