Click to expand...

1. Click fc105 and Press F1 for more information.
2. To see INT values, just put your AI address in VAT table and monitor for example PIW256
S7 will translate for you based on your HW configuration.
3. if you want to scale This INT values to ., for example (0 to 10 bar) then u have to use FC105.
