Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C

Considerations With This Ladder Logic Example

Remember the following when using this method of module reconfiguration
using the reset service.

• When this method of reconfiguration is used on output modules, ALL

module outputs will be reset to zero for at least three seconds.

• This method of reconfiguration will cause a Major Fault in the

controller if the module was initially configured to do so on the
following window.

• All Listen-Only controllers will lose their connections to the module for

a minimum of three seconds after the Reset is performed.

• If the Reconfiguration is performed on an input module with multiple

owners, then all owners will lose their connections simultaneously after
the Reset is performed. In order to re-establish all their connections, all
owners must change their configuration to the same values BEFORE
the Reset is performed.

IMPORTANT

The considerations listed in this section apply only if you are
using RSLogix 5000 software, version 9 or earlier.

If you are using RSLogix 5000 software, version 10 or later,
none of these considerations apply.

Choose a Major Fault
in controller here.
