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.

steps:

1. Check all connections.

2. Power on the bus.
