(3) Example of the combined use of the digital clipping function and the scaling
function
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"
1. Set "Parameter write" for "Method selection".
"CC IE Field Configuration" window Select the main A/D converter module from "List of stations"
[CC IE Field Configuration] [Online] [Parameter Processing of Slave Station]
2. In "Basic module parameter", set "CH A/D conversion enable/disable setting" to "0: Enable".
