DeviceNetManager software is a tool used to configure your FLEX I/O
DeviceNet adapter and its related modules. This software tool can be
connected to the adapter via the DeviceNet network.
You must understand how DeviceNetManager software works in order to
add a device to the network. Refer to the DeviceNetManager Software
User Manual, publication 1787-6.5.3.
Output data is received by the adapter in the order of the installed I/O
modules. The Output data for Slot 0 is received first, followed by the
Output data for Slot 1, and so on up to slot 7.
The first word of input data sent by the adapter is the Adapter Status
Word. This is followed by the input data from each slot, in the order of the
installed I/O modules. The Input data from Slot 0 is first after the status
word, followed by Input data from Slot 2, and so on up to slot 7.
