FLEX I/O DeviceNet Adapter Module
Enhancements to Firmware 3.001
Firmware revision 3.001 provides the following functionality to the 1794-ADN
DeviceNet adapter.
• When you cycle power to the adapter in out-of-the-box mode (no rack
configuration stored in the memory of the adapter), and there is a 32-
point input or output module (1794-IB32 or 1794-OB32) on the rail,
the adapter will detect the 32-point module as a 2-word module and
allocate I/O space appropriately for the network connection.
• With firmware revision 3.001, when you cycle power to the adapter in
out-of-the-box mode, if a 1794-IB32 module is detected, it will allocate
two input words, and no output words, for the network connection.
Similarly for the 1794-OB32, two output words, and no input words,
are allocated for the network connection.
