5. Fault Finding and Maintenance
5.1. Fault Reporting
Input module faults are reported to the user through visual indicators (LEDs) on the front panel of the
module. Faults are also reported via status variables which may be automatically monitored in the
application programs, and external system communications interfaces. There are generally two types
of faults that must be remedied by the user; external wiring and module faults. External wiring faults
require corrective action in the field to repair the fault condition. Module faults require replacement of
the module.
5.2. Diagnostics
The Windows XP diagnostics (e.g. Event Log, Device Manager) can be accessed by connecting to the
Gateway module using the Remote Desktop Connection facility from another Windows XP PC.
When additional software is installed (e.g. the OPC Server) the software’s diagnostic information can
be accessed in the same way. See the appropriate Product Description for details.
5.3. Backup
Having configured the Gateway Module and commissioned it to a working state, a backup or
configuration record should be considered. The Gateway Module should be treated as a standard
Windows PC in this respect.
It is possible to take a complete snapshot of the disk drive as a ‘ghost image’ using commonly
available utilities. In this case, note that any subsequent changes will not be recorded in the ghost
image. These will include updated OPC Server databases. However, it is possible for the Gateway
Module to access this application data on a remote PC, and so a reinstalled ghost image will
automatically reload the latest configuration. However, note that if the Gateway module is replaced, the
new module is a new PC and Windows XP will search for the same MAC address on the PC before
accepting its license status; it may not run.
An alternative is to record all configuration details during installation. Using the procedure in this PD,
record details like the computer name, IP addresses, username and password, workgroup
configuration, automatic logon, program installations/configuration and mapped network drives. In this
instance the information may be used on any new Gateway module or other PC.
