It appears that I cannot use object visibility options with floating pt 32 tags with the C-More touch panel. In a previous program, I used to have integer tags for temperature transmitters that, when a 4-20mA transmitter was unplugged, the numeric display object became invisible (I used the argument of address value > 819 which is the 4mA reading). I had to reprogram the PLC to use floating point for these transmitters so that I could take advantage of trending/datalogging the tag values in engineering units and now I 've lost the ability to make the numeric display invisible when the transmitter is out of action. Any suggestions on how I can use the visibility option given that my PLC tags are floating pt 32? I use a DL350 cpu and a c-more panel. Thanks John

Write some ladder code in the PLC that uses comparison statements to turn on a bit when you want the objects visible. Then use that bit as your visibility tag.
