Rockwell Automation 1794-APB/B FLEX I/O PROFIBUS Adapter Module User Manual - Manual (Page 24)

2–4 How Communication Takes Place and I/O Image Table Mapping
Publication 1794ĆUM057B-EN-P - November 2001
Possible causes for an I/O module fault are:
•
transmission errors on the FLEX I/O backplane
•
a failed module
•
a module removed from its terminal base
•
incorrect module inserted in a slot position
•
the slot is empty
The node address changed bit is set when the node address switch
setting has been changed since power up. The new node address does
not take effect until the adapter has been powered down and then
powered back up. Until this power cycling occurs, the node address
switches will not match the actual node address.
FLEX I/O modules presently supported by the PROFIBUS adapter
are listed below. Additional modules will be added as they are
developed.
