DeviceNet Manager is a software 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 know and understand how DeviceNet Manager works in
order to add a device to the network. Refer to the DeviceNet
Manager 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.
