I/O-channels and Diagram mode, strange issues when downloaded and settings are written over
Hi all, I have a delicate problem while programming a number of RTD temperatures to a PM851 in diagram mode. I this case, my project consist of nine controllers and all of them is included in the same project file. I´ve have already figured out that I can´t put all the (hundreds) of RTD´s in a global list for each CPU (can´t be reached when programming) so I have to declare each bundle locally in each CPU. So far so good. The problem occurs when I declare each channel/RTD in the I/O (AI830) that no matter what setting I use the temperature range in the "Properties" tab will be set to 0-100 when online. Even specifying a range of -200 to 800 degree C the min and max range will be reset to 0-100 when downloading and running. I never had any problem with this before, just when I started to program in the Diagram mode. How can I set up and connect variabels to I/O channels that doesn´t change the min/max range? They are only used in a single diagram in each CPU. I´m would be sooo grateful for any tip on this. I´m using Compact Control Builder 6.0.0/2.

Hello!
I have not used that function block myself but looking in the help file it states that the IO-variable should not be connected to this function block. The I/O channel range will be overwritten.
