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	Invalid value recorded at one of the floating point 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 a floating point value calculation
Bit 8 = 1	256	0x0100	True	T_DELAY exceeds the maximum value that can be reached on the BUFFER output

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

Error message

This error appears if a non floating point value is entered at an input or if there is a problem with a floating point calculation. In this case the outputs OUT and BUFFER remain unchanged.

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

Alarm

There will be an alarm if a T_DELAY exceeds the maximum possible value. In this case the function block uses the maximum value. If an outgoing value is required, which is above the default value, only the BUFFER-output needs to be linked to a larger variable.
