Runtime error

Status word

The bits of the status words have the following meaning:

Bit	Value in Dec.	Value in Hex.	ENO Status	Description
Bit 0 = 1	1	0x0001	False	Error in a calculation in floating point values
Bit 1 = 1	2	0x0002	False	Recording of an invalid value of a floating point value input
Bit 2 = 1	4	0x0004	False	Division by zero with calculation in floating point values
Bit 3 = 1	8	0x0008	False	Capacity overflow during floating point value calculation
Bit 4 = 1	16	0x0010	True	One of the following variables is negative: IN, pu, PA, TA. For calculation, the function block uses the value 0.

For the list of other possible floating point error codes, see Common Floating Point Errors.

Error message

In the following cases an error will be reported:

An invalid value will be recorded at one of the floating point inputs
Division by zero with calculation in floating point values
Capacity overflow during floating point value calculation

The output OUT will not be altered.

NOTE: For a list of all block error codes and values, seeConditioning.

Warning

A warning is given if the parameter pu is negative, in this case with the calculation the block can use the value 0 in place of the defective value pu.
