When using the "cpt" compute function to change the signal count to percent, I said divide by "24968.0" and then entered "24984.0" by mistake. This creates a slight error in the "Transmitter_Input_Percent" variable (tag).

You don't need an Ethernet adapter and Flex I/O analog modules. Just configure SoftLogix for the modules and it builds the data structure in the controller tags to use in the program. Just put some ethernet network address in the ethernet adapter such as 0.0.0.0 for the ip address.
