Digital Clipping Function
The range of a digital operation value is fixed between the maximum digital output value and the minimum digital
output value if the input voltage or current exceeds the input range.
(1) How to interpret the digital clipping setting
The following table shows how the output range of a digital output value changes by enabling the digital clipping
function for each range.
Input range
4 to 20mA
0 to 20mA
1 to 5V
0 to 5V
-10 to 10V
User range setting 1 (-10 to 10V)
User range setting 2 (-5 to 5V, -20 to 20mA)
(2) Setting procedure
The setting procedure for the main A/D converter module is as follows:
1.
Set "Method selection" to "Parameter write".
"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".
3.
In "Basic module parameter", set "CH Digital clipping enable/disable setting" to "0: Enable".
For the extension A/D converter module, make the settings for each item of "Ext. module 1_Module parameter".
Output range of a digital operation value
Digital clipping function disabled
-384 to 16383
-16384 to 16383
