0x0001
False
Error in a floating point value calculation
Bit 1 = 1
2
0x0002

The following behavior is displayed:
  • SP lies outside the area [pv_inf, pv_sup]: SP is limited to pv_inf or pv_sup
  • dev_ll > 0 or dev_hl < 0: the block uses the value 0
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. The output OUT is then set to 0; the outputs DEV and MA_O remain unmodified.
NOTE: For a list of all block error codes and values, see Controller.
Warning
A warning is given if dev_ll > 0 is dev_hl < is 0 In this case the function block uses the value 0.
