TSTALM Module 3,11,06 Block 24080 checks subsequent Block 24084

This message tells you that a TSTALM block has a lower block number than the block whose status it is testing. This may often be ignored, because there are ways of making the block processing not follow block numbers.

These messages exist because in a redundant module switchover, the first scan of the module may have indeterminate or incorrect values for the blocks being tested, as it will not have been executed.

When the TSTALM block has a lower block number than the block it is testing, it executes first in the cycle, therefore it will test the value of the block, taken in the previous cycle.

The test block, (2855), is before the block being tested, (in this case 7011).

This message shows a potential error in the system configuration, although most such errors prove to be harmless. It should be reviewed and hidden, unless it shows an issue that should be addressed.
