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 input TR_I or one of the parameters thld or cutoff are negative: For calculation, the function block uses the value 0
Bit 6 = 1	64	0x0060	True	The count register cter has reached its maximum value (65535): cter is locked at this value and the output outc no longer has any meaning. The OUT and done outputs can however continue to be used.

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

Error message

A runtime error is signaled if a non floating point value is recorded or if there is a problem with a floating point calculation. In this case the OUT, outc, cter and done outputs remain unmodified.

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

Warning Message

In the following cases a warning message is given:

If...	Then...
thld < 0	For calculation, the controller uses the value 0
cutoff < 0	For calculation, the controller uses the value 0
cter = 65535	cter is blocked at this value and the output outc no longer has any meaning. The OUT and done outputs can however continue to be used.
