BLOCK_ERR: The block error parameter reflects the error status of associated hard-
ware or software components and directly impacts the correct operation of a block.
Block errors will notified as block alarms.
Description
For the resource block, Simulate Active will be used to indicate that the simulate
hardware jumper is present. An active state (1) of this attribute will indicate that the
jumper is present and that it is possible for the user to enable simulation in an input
or output class function block.
detected by this block/process variable has a status of BAD, Sensor Failure
detected by this block/back calculation input has a status of BAD, Device Failure
XD_ERROR: An additional parameter, XD_ERROR, must be used to hold the single
error subcode that the manufacturer considers most important when one or more
errors occur. BLOCK_ERR will have bit 0 set whenever XD_ERROR is non-zero.
Description
An error has occurred that was not identified.
An error has occurred that could not be classified as one of the errors below.
An error occurred during calibration of the device or a calibration error has been
detected during operation of the device.
An error occurred during configuration of the device or a configuration error has
been detected during operation of the device.
An electronic component has failed.
A mechanical component has failed.
An I/O failure has occurred
Indicates that data stored within the system may no longer be valid due to NVM
checksum failure, Data verify after write failure, etc.
The software has detected an error. This could be caused by an improper interrupt
service routine, an arithmetic overflow, a watchdog timer, etc.
The algorithm used in the transducer block produced an error. This could be due to
an overflow, data reasonableness failure, etc.
