Cause : Floating Point exception - An exception occurred during an operation with the FloatingPoint data type. The error may be caused by the basic system or an OA application (e.g., FBLOCKS, DCC)

Note: Refer to r9999 for further information about this fault.


r9999[0]: Fault number.
r9999[1]: Program counter at the time when the exception occurred.
r9999[2]: Cause of the FloatingPoint exception.
Bit 0 = 1: Operation invalid
Bit 1 = 1: Division by zero
Bit 2 = 1: Overflow
Bit 3 = 1: Underflow
Bit 4 = 1: Inaccurate result

Remedy:

- carry out a POWER ON (power off/on) for all components.
- check configuration and signals of the blocks in FBLOCKS.
- check configuration and signals of DCC charts.
- upgrade firmware to later version.
