PM591 FPU exception callback function doesn't run. Help needed
I try to catch EVENT_EXCPT_ FPU_OVERFLOW error. For that I register my callback like this: registeredD := SysCallbackRegister(iPOUIndex:=INDEXOF(CallbackFPUOwF), Event:=EVENT_EXCPT_FPU_OVERFLOW); But my callvbackfunction does'nt run. I also disabled my Reaction on floating point exception since I want to catc that exception myself and not crushing PLC. Maybe someone has working example or some suggestions about that problem.
