Continuous exception reports generated by Module 10,05,02 Block 3900 (FC 30):  Significant change value is 0.0.

The block shown will generate an exception report on any change of value. This may be intentional, but can also be an error.

If a value comes from some external source and is rarely changed, this technique assures that the change will be immediately deployed to graphics and other import blocks. After that, the static input means that no extraneous exception reports will occur.

On the other hand, if the input is a dynamic analog value, it may well change every time it is read. This means that an exception report will typically be generated every second, which is why this is brought to your attention.

These messages are only generated when exception reports occur. Exception reports actually do not occur from all exception report blocks. They are generated only on two conditions:

• the block is enrolled in a database in a CIU serving a console or historian
• the block is imported by an exception report importing block

Example:

--Scanning drawing A050292: AS-SHIPPED

This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
