bcd to integer

[Simon]

my plc uses bcd formated analog values. when importing into daqfactory, is there an easy way to convert to integer?

[AzeoTech]

Yup. Here is the formula:

sum((bcd & {0xf000,0xf00,0xf0,0xf}) / {4096,256,16,1} * {1000,100,10,1})

where bcd is the bcd encoded value. The result is an integer.

it works perfectly. but it leads me to another question: is this conversion documented somewhere? how could i have found this by myself?

[AzeoTech]

The technique used is documented, but the conversion itself isn't. We can't document every possible formula, or every possible application. The manual is already 440 pages long. However, because you were good enough to post the question to the forum, now it is documented for other users. For things not in the manual and not in the forum already, you can just do what you did: ask.
