4.8 Faults / Diagnostics
4.8.1 Configuration Faults
Faults in the Expansion Module configuration/parameterization data are handled slightly differently depending on when they
are detected. In any case the following occurs:
•
200X Adapter Object AdapterStatus attribute indicates the appropriate code
•
Identity Object status attribute indicates a minor recoverable fault
Fault detected at powerup or as a result of a hot-swap when no I/O connections are open
•
Any attempt to allocate I/O connections will be rejected by the device
Fault detected as a result of a hot-swap when one or more I/O connections are open
•
I/O connection(s) produce zero-length data or, if the
IoStatusEnable
attribute is TRUE a fault will be indicated in the
I/O Status byte at the beginning of the input data packet.
•
Output data from master is ignored
•
Any attempt to allocate I/O connections will be rejected by the device
4.8.2 Configuration Fault Recovery
Recovery from configuration faults is achieved by:
•
Installing/removing I/O module(s) to make the actual configuration match the user-defined configuration
•
And/or changing the configuration data to match the actual configuration and either restarting/resetting the adapter
4.8.3 Expansion Module Faults
Faults in Expansion Modules are reported as follows:
•
Serious faults (as determined by the Adapter) force the produced I/O data to zero-length or, if the IoStatusEnable
attribute is TRUE a fault will be indicated in the I/O Status byte at the beginning of the input data packet.
•
The appropriate Slot Object instance SlotStatus attribute and Channel<n>Status attribute(s) indicate the nature of the
fault
•
I/O Status LED state will be Flashing Red
4.9 Module Hot Swap
The 5136-DNS-200X does not support Expansion Module hot-swap.
