Hello Iyyappan S; The value 27648 has simply been selected as the maximum normal range value of any analog signal transfered to the CPU by a Siemens analog module.This numerical value is independant of the resolution of the particular analog module used (this is a way to standardize all scaling of analog readingsin the processor) For unipolar data, this would mean 0 to 27648 represents full range; above 27648, overrange, below 0, underrange.See the attached illustration for the equivalent numeric values iof a 4-20 mA or 0-20 mA signal. The basic configuration of the analog modules is best explained in the S7-300 module Data manual: http://support.automation.siemens.com/WW/view/en/8859629 Look at the chapters on Principles of Analog value processing and Representation of the analog values of analog modules. Hope this helps, Daniel Chartier |
