I have a waveform record which reads consecutive values from hardware memory (happens to be Modbus over ethernet). I then use a subArray record to pick out individual values. However if the hardware goes off-line (so the waveform is temporarily invalid) the subArray record changes its INDX field to 0! When the hardware comes back on-line the subArray record now points to the wrong location in the waveform. Is this intended? Suggestions for avoiding this situation?
