Applies to:

PcVue all versions.
Summary:

Some PLC programs use some bits in “Inverse logic”. We need to invert them for PcVue.
Details:

PcVue can do it automatically – but you cannot configure it in a dialog box but in the Varexp.dat directly.
For each bit check the column AH (Format) and replace “B” by “b”.

Note: This feature is available only for Equipment variables.
