However, in some cases, users mayneed to calculate or display decimals. Here we provide a work-aroundmethod to handle decimals.Take I-7017Z for example. Supposed that we use I-7017Z to read ananalog value 3.265V back from a remote equipment and we want toutilize the powerful feature of HMIWorks, Ladder Designer. However,Ladder Designer supports only integers. So we must handle thisdrawback to directly read back the AI value from I-7017Z in LadderDesigner.1.

Let the read back AI valuemultiplied by ten of the n-th power where n is the value of“DecimalDigits”. You can find out I/O module’s IO.hsf file in thefollowing locations: “[HMIWorks_install_path]\ bin\Modules\”.For example, IO.hsf of I-7017Z is located in
