Installing a Replacement
DeviceNet Adapter in an
Existing System
Your existing control application may be using another DeviceNet
adapter (e.g., 1734-PDN) that you want to replace with a
1734-ADN(X) DeviceNet adapter. Remove the existing adapter from
the DIN rail
as follows:
1. Eliminate power to the adapter and all I/O modules in your
existing system.
2. Remove the wiring assembly and DeviceNet cable from your
existing adapter.
3. Remove the adjacent I/O module.
For information on how to remove POINT I/O modules from the
DIN rail, see the associated publications for those modules.
4. Use a small bladed screwdriver to rotate the DIN rail locking
screw to a vertical position and release the locking mechanism.
5. Pull the adapter off of the DIN rail to remove it from the
existing system.
