Replacing Devices

You can use the Segment Controller to replace a device if the device fails or a

newer version of the device becomes available. Note the following requirements

when replacing a device:

•

The replacement device must have the same program ID as the original

device.

•

The application image file and device interface should match the original

device; otherwise, you might have to upgrade the replacement device as

well.

If you replace a device that was serving as a repeating agent, the Segment

Controller automatically identifies alternate repeating devices to relay network

messages to those target devices that were using the old device in their repeating

chains. When you add the replacement device to the network, the Segment

Controller attempts to commission the replacement device. The commissioning

succeeds if the Segment Controller can communicate with the device either

directly or through a repeating chain.
Note: If the original device still functions, leave the old device connected to the

network (if physically possible) until the device replacement has been completed.

Thus, the Segment Controller can decommission the old device so that you can

easily reuse it in a new network. This step is not required if the device has

failed.
To replace a device with the Segment Controller, perform the following steps:

1. Attach the replacement device to the network by applying power to the

device and attaching its network connection as documented by the device

manufacturer.

2. Right-click the original device, select Manage, and then select Replace

from the shortcut menu.
