Faults

Configuration faults
Faults in the electronic module configuration and parameterization data are handled slightly
differently depending on when they are detected.
Regardless of the detection time, the following occur:
● The Adapter Object AdapterStatus attribute indicates the appropriate code.
● The Identity Object Status attribute indicates a minor recoverable fault.
When the fault is detected at power-up or as a result of a hot swap when no I/O connections
are open:
● An attempt to open I/O connections results in a Device State Conflict error.
A fault detected as a result of a hot-swap when one or more I/O connections are open result
in the following behavior:
● 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 the scanner is ignored.
● Any attempt to allocate I/O connections is rejected by the device.
You can recover from the configuration fault by:
● installing or removing I/O modules 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
EIP ET200 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.
