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.
