Introduction
BME NUA 0100 provides diagnostic and descriptive information.
Items for Connection Diagnostic
To diagnose the connection status with the time stamping event sources the following item is available:
#PLCQualStatus
It can return one of the following values:
QUAL_BAD + QUAL_COMM_FAILURE (value 0018 hex): Device is INCONSISTENT (SymbolFile differs from PLC application).
QUAL_BAD + QUAL_DEVICE_FAILURE (value 000C hex): No communication with the device since DEVICE_TO milliseconds.
QUAL_BAD (value 0000 hex): Device is MISSING or UNKNOWN.
QUAL_GOOD (value 00C0 hex): Communication with the device is correct.
QUAL_UNCERTAIN (value 0040 hex): No communication with the device since less than DEVICE_TO milliseconds.
Managed Informational Items of the BME NUA 0100
These items include:
#AppliName: Name of the application read from the PLC.#AppliVersion: Version number of the application read from the PLC.#DeviceIdentity: Device type.#CurrentMonitoredItemsCount: Current monitored item count for all simultaneous sessions/clients.#TSEventSynchro: A read/write BOOL item that, when activated, sends a synchronized value to the entire at source time stamping devices attached to the M580 ePAC, each time a write operation is performed. The purpose is to initialize all the timestamped monitored items to their current values.#TSEventItemsReady: A read-only BOOL item that indicates whether source time stamped variables and source time stamping devices have been browsed in the M580 ePAC application.#PLCQualStatus: 0 if QUAL_BAD, 12 if QUAL_FAILURE, 40 if QUAL_UNCERTAIN, 192 if QUAL_GOOD.#PLCDataDicReady: 1 if PLC data dictionary is not available, 2 if PLC data dictionary is available, 4 if PLC data dictionary is busy.#AddressSpaceState: 0 when address space is empty, 1 if address space is built, 2 when address space is updating, 3 if address space is partially built.#CurrentDataDictionaryItemsCount: Number of variable in data dictionary - negative values are displayed if an error is detected.
