ad_conv

Some PLC models has one or more analog to digital converters. This device allows you to aquire analogs value and convert it in a numerical value. The value supplied by the converter is normalized in the range 0-65535 indipendently by the converter resolution. Two parameters, called OFFSET and SPAN, are available to change the converter dynamic. The OFFSET parameter adds a base value to the converted value and the SPAN parameter changes the converter gain.

With values OFFSET=0 and SPAN=1.0 no alteration will be applied to the converted value. SPAN values greater than 1.0 produce a gain, SPAN values less than 1.0 produce value attenuation.
