Runtime error

Status word

The following messages are displayed in the Status word:

Bit	Value in Dec.	Value in Hex.	ENO Status	Description
Bit 0 = 1	1	0x0001	False	Error in a floating point value calculation
Bit 1 = 1	2	0x0002	False	Recording of an invalid value on one of the floating point value inputs
Bit 2 = 1	4	0x0004	False	Division by zero during a floating point value calculation
Bit 3 = 1	8	0x0008	False	Capacity overflow for a calculation with floating point values
Bit 4 = 1	16	0x0010	True	The input K (or RK) is outside the range [k_min, k_max]: For calculation the function block uses the value k_min or k_max.
Bit 5 = 1	32	0x0020	True	The output SP has reached the lower threshold sp_min: SP is limited to sp_min
Bit 6 = 1	64	0x0040	True	The output SP has reached the upper threshold sp_max: SP is limited to sp_max

Error message

The error appears if a non floating value is recorded or if there is a problem with a floating point calculation. The outputs KACT and SP remain unmodified.
