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	The following behavior is displayed: SP lies outside the area [pv_inf, pv_sup]: SP is limited to pv_inf or pv_sup in this case. dev_ll > 0 or dev_hl < 0: the block uses the value 0 hyst is outside the [0, Minimum (dev_hl, -dev_ll)] range: the block uses a value limited to zero or to minimum (dev_hl, -dev_ll)

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

Error message

An runtime error appears if a non floating point value is recorded or if there is a problem with a floating point calculation. In this case the outputs OUT_NEG and OUT_POS are set to 0; the DEV and MA_O outputs remain unmodified.

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

Warning

In the following cases a warning is given:

dev_ll > 0 or dev_hl < 0: the block uses the value 0.
hyst is outside the [0, Minimum (dev_hl, -dev_ll)] range: the block uses a limited value.
