I have action Item with command
where StopBit and FaultRegister are OPC Items,
when StopBit and FaultRegister have good opc quality than action item shows correct value,
when StopBit have good quality and FaultRegister bad quality than action item have also bad quality, and this is correct,
but when StopBit have bad quality than action item have good quality and value = 0.
is there any function to check quality of opc item?
