This unit is transferred automatically into the corresponding integer value (according to IEC
61158) during the transfer to PCS 7.
Note
To change the unit group you need COMOS administrator rights or the function rights "Base
data".
You can find more information on this topic in the "COMOS Platform Administration" manual,
keyword "Using the "Rights" tab": Assigning function rights".
Note
Exchange of Low Scale / High Scale / Unit values between PAA and PCS 7 in the Import /
Export PCS 7 plugin
You have a "Signal attributes high- low scale, unit" option in the "Miscellaneous" area of the
"Filter" group in the "Import / Export PCS 7" plugin. By default, the "Signal attributes high-, low
scale value, unit" option is selected when the "Import / Export" plugin is opened.
If you wish not to import these attributes as you are using a PCS 7 Library where you have
defined Low Scale / High Scale or Unit as separate technological I/O parameters, unselect this
option.
