(3) Example of the combined use of the digital clipping function and the scaling
function
Ex. For the channel with the set input range of 0 to 5V, of the main A/D converter module, settings are made
as follows:
• "CH  Scaling enable/disable setting": "0: Enable"
• "CH  Scaling upper limit value": 24000
• "CH  Scaling lower limit value": 0
• "CH  Digital clipping enable/disable setting": "0: Enable"

Set "Parameter write" for "Method selection".
"CC IE Field Configuration" window  Select the main A/D converter module from "List of stations"
