In other networking systems like A-B RIO, the memory location in the controller corresponds to the network address and slot number of the 1794 FLEX I/O module. With DeviceNet, however, the memory location in the controller for a 1794 FLEX I/O module is entirely dependent on the "mapping" that you perform in RSNetworx for DeviceNet. Generally, FLEX I/O uses 16-bit data elements, while the 1788-DNBO uses 32-bit data elements. You will probably have to use COP instructions in ladder logic to sort out the FLEX I/O data from the Input and Output tags of the 1788-DNBO.
