| One solution is to
configure your Variable Tag with a CitectSCADA native data type
(e.g. INT) which means that CitectSCADA will represent your Hex
value as an Integer (e.g. If you have 31 Hex stored in the PLC,
CitectSCADA will read 49). However, if you would like to display 31
on a page or in a Cicode function, you can use the HexToStr Cicode
function to convert it.
Another possible solution is to set the data
type to BCD or LongBCD which will allow you to read/write the hex
value without having to do any Hex-to/from-String conversions. It
is important to note however that this solution will only work for
Hex values containing numeric digits (i.e. 0-9, but not
A-F).
