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 during floating point value calculation
Bit 4 = 1	16	0x0010	True	IN or one of the parameters out1_th1, out1_th2, out2_th1, out2_th2 is not in the range [0, 100]: for calculation, the function block uses the value 0 or 100.
Bit 5 = 1	32	0x0020	True	The output OUT1 has reached the lower threshold out1_inf: OUT1 is forced to out1_inf.
Bit 6 = 1	64	0x0040	True	The output OUT1 has reached the upper threshold out1_sup: OUT1 is forced to out1_sup.
Bit 7 = 1	128	0x0080	False	Both the threshold values of an output are identical: out1_th1 = out1_th2, out2_th1 = out2_th2.
Bit 8 = 1	256	0x0100	True	The output OUT2 has reached the lower threshold out2_inf: OUT2 is forced to out2_inf.
Bit 9 = 1	516	0x0200	True	The output OUT2 has reached the upper threshold out2_sup: OUT2 is forced to out2_sup.

Error message

A runtime error appears in the following cases:

A non-floating value is on an input
A problem has occurred during a floating point value calculation.
Both the thresholds of the same output are identical: out1_th1 = out1_th2 or out2_th1 = out2_th2

The outputs OUT1 and OUT2 are never modified.

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

Warning

A warning is given if one of the parameters out1_th1, out1_th2, out2_th1, out2_th2 is not in the [0 - 100] range. In this case the function block uses the value 0 or 100 for calculating.
