Faults / diagnostics

Configuration faults
Faults in the electronic module configuration/parameterization data are handled slightly
differently depending on when they are detected. In any case, the following occurs:
● Adapter Object AdapterStatus attribute indicates the appropriate code.
● Identity Object Status attribute indicates a minor recoverable fault.
Fault detected at power-up or as a result of a hot swap when no I/O connections are open:
● Attempts to open I/O connections result in a Device State Conflict error.
Fault detected as a result of a hot-swap when one or more I/O connections are open:
● If the IO_StatusEnable attribute is TRUE, a fault is indicated in the I/O Status byte at the
beginning of the input data packet.
● Output data from scanner is ignored.
● Any attempt to allocate I/O connections will be rejected by the device.
Configuration fault recovery 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.
The I/O configuration is reapplied immediately after a configuration download from the
ZNX-EIP-200S Configuration Tool, and at module startup.
Electronic module faults
When an I/O connection is active, faults in electronic modules are reported as follows:
● If the IO_StatusEnable attribute is TRUE, a fault is 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.
● The I/O status LED state is flashing red when I/O is active.
