Reporting Diagnostic Condition To The Host; Diagnostic Events Reported By Block Error - GE Baker Hughes Masoneilan SVI FF Installation And Operation Manual

Reporting Diagnostic Condition to the Host

All parameters related to the diagnostic alerts are described in the DDs and can be read by
the host at any moment. The SVI FF DTM also provides a detailed graphical presentation
about the current and historic diagnostic conditions detected by the device.
Monitoring a significant number of parameters and conditions can create a significant traffic
on the bus and may not be convenient. To avoid this, the SVI provides several levels of
simplification, which allows reporting the device status to the operator in the plant, but also
provides additional details to the device specialists.

Diagnostic Events Reported by Block Error

Setting the parameters in the Block Error parameter provides a good level of abstraction. The
detected failure is mapped to one of the bits in BLOCK ERR as follows:
Device Needs Maintenance Now
Device Needs Maintenance Soon
NV Memory Failure, etc.
All hosts monitor the errors reported by the BLOCK_ERR parameter and the information is
immediately indicated to the operator with the level of urgency required.
For the hosts that do not support Transducer blocks, the diagnostic indication is duplicated in
the resource BLOCK_ERR parameter.
Some DCSs monitor the status of the BLOCK_ERR parameter and automatically generate
notification alarms to the operator. Similar device status alarms are also generated if the
communication to the device is disturbed or if the DCS detects other device failures.
