If you are reading a multiple channel tag and one or more channels is(are) in an Open Loop condition, then you will receive a warning from the FP Read or FP Write. However, this warning simply tells you that one or more channels has reported an Open Loop condition. If you need to figure out which channel is specifically reporting the Open Loop condition, you have to read/write each channel individually to get the channel status for a particular channel.
