Communicate With Your Module 33
The adapter input status word bit descriptions are shown in table Word Bit
Description on page 33.
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.
Defaults
Each I/O module has default values associated with it. At default, each module
generates inputs/status and expects outputs/configuration.
