I am using scan mode of cRIO-9074 to control and measure a furnace. Everything is OK except the reading. When the reading values of temperature are more than 1000, then they are foced to 0. I use NI Distributed System manager to check. The reading values of all the modules have same problem, even for the reading of current. When I force the value less than 1000 (such as 999), it is OK and displays the same value, but when the value is equal to or more than 1000, the ForceValue changes to 0. Is there anyone knows what the problem is? Thank you very much.
