Table 1-1 OSx @aGlance Troubleshooting
Problem Solution
OSx goes to Offline state, and you
get a
Network Transport E rror
message.
When OSx returns to Operate state, try again to read data. If you want
to write to tag values, you must log in again.
Unexplained Network Transport Error
message appears.
Try requesting data again before assuming an error. Then check the
state of the OSx station, which may have failed, developed
communication problems, or changed to the Offline state. Verify the
client configuration of the OSx station address.
With two OSx networks installed,
either one network or one network
card in the OSx station fails.
You must re-register station names and addresses before using the
alternate network. Use the A/B network designation after the station
name.
For Linux, UNIX o r VMS users: contact your system administrator.
For Windows users, follow these steps:
1. Either switch cables on the client to the other network, or
toggle the T-Box switch to the other network.
2. Access the Windows Network Setup (in the Program Manager)
and configure the client to use the other network.
3. Exit and restart Windows.
A Network Transport Error (Remote
system error; Connect request refused
)
appears.
This indicates a network problem, such as pulled or broken cable at the
client. This can cause the @aGlance server to shut down at the OSx
station where you are connected. Correct the problem and then connect
to another station where @aGlance is loaded to resume your @aGlance
work.
In order to restart the server o n the original station, transition OSx to
the Offline state and then back to Operate again. To avoid setting all
OSx stations Offline, you can follow these steps instead.
1. Set the station where the server has shut down to Out_of_Service.
2 Shut do wn the s ta ti o n b y s e l e cti n g
Controls ->Change S ystem S tate
on the menu bar and choosing Shutdown OSx and Linux.
3. When the Power down message appears, power down the
station and power it back up again after 15 seconds. When the
station rejoins the system, it automatically resynchronizes with
the primary and restarts the OSx @aGlance server.
OSx host station goes to Failed
state.
You must re-register station names and addresses from the client side.
Unexpected data, such as #N/A
(data not available), #REF
(communication problem), or
#NAME? (invalid syntax), appears in
spreadsheet cells.
It is probably a communications failure. Resolve the network problem
and reissue the cold link command. Hot links clear automatically when
you view them. If
#NAME appears in a cell instead of values expected,
check the @aGlance/IT DDE server message window for a message
indicating that the server has gone out of service.
