Illegal spec value for Module 2,31,07 Block 2446 (FC 30): Spec S7 has value -100000, should be 0.0 to 100.0
The specification shown is not a legal value, according to the documentation.
In the case of S7 of AO/L: Analog Exception Report [FC30], we can guess that the block will not properly handle exception reports.
The message always means that the specification violates the limits that are documented. In the FC 30 example, the value of S7 tells how much change causes an exception report. We have to guess that a negative value is the same as 0.0, and will cause an exception report anytime the input changes. The default value is 1 (%) and the value of S7 should be corrected.
