Range Switching Function

The output range can be selected for each channel from the following ranges:
• Factory default range (4 to 20mA, 0 to 20mA, 1 to 5V, 0 to 5V, -10 to 10V)
• User range (user range setting 1 (-10 to 10V), user range setting 2 (0 to 20mA))
*1 The main D/A converter module only permits the selection.
(1) Setting procedure
The setting procedure for the main D/A converter module is as follows:
1.
Set "Method selection" to "Parameter write".
"CC IE Field Configuration" window  Select the main D/A converter module from "List of stations"
[CC IE Field Configuration]  [Online]  [Parameter Processing of Slave Station]
2.
In "Basic module parameter", set "CH D/A conversion enable/disable setting" to "0: Enable".
3.
In "Basic module parameter", set up "CH Range setting".
● When switching the output range, set CH Output enable/disable flag (RY10 to RY13, RY20 to RY23) to Disable (OFF)
before setting a value (within the range an external device allows) for CH Digital value (RWw2 to RWw5, RWw12 to
RWw15).
For example, when the output range is from 0 to 5V and CH Digital value (RWw2 to RWw5, RWw12 to RWw15) is
12000, 5V is output. In this condition, if the output range is changed to -10 to 10V, 7.5V is output because CH Digital
value (RWw2 to RWw5, RWw12 to RWw15) remains 12000.
● For the extension D/A converter module, make the settings for each item of "Ext. module 1_Module parameter".
