Troubleshooting and Common Questions B-3
Device Problems
If you receive a status of Bad:Device Failure, set the RESTART
parameter in the Block window to Processor or Default. If the
problem persists, replace the device.
If a device does not accept a permanent address, you must set the
device tag. For instructions on setting the tag, refer to the Setting
Device or Block Tags on page 4-5. If the device already has a tag, the
T3 network parameter might not be the right length. To solve this
problem, remove the device from the active bus and configure its
address separately.
If a device does not accept a new tag, it might be in an invalid state.
To solve this problem, power the device off and on.
