Changing the Default IDN Parameter Values Appendix E
Write the New IDN Parameter Value
Follow these steps to write the new IDN parameter value.
1. Configure a Message Configuration (MSG) instruction to write the
IDN parameter value required for your application.
In this example, the Message Configuration (MSG) instruction is set to
write the additional bus capacitance of your leader IAM power module.
a. From the Message Type pull-down menu, choose Sercos IDN Write.
b. From the Identification Number pull-down menus, choose P-0-99.
2. Click New Tag.
3. The New Tag dialog box opens.
4. Type the name of your Source tag.
In this example, the tag name is Write_Value.
5. Click OK.
In this example, the new tag creates a source value (that you entered)
that the MSG instruction uses to overwrite the existing P-0-099 IDN
value.
