Temporary Devices
It may be desirable to have devices temporarily integrated into a network
supervised by a device manager. Portable test equipment, for example, might
need to be bound into the network for service, but generally would be absent
when the network is running under normal conditions. In such cases it is usually
better if the device is not pinged by the Device Manager. Such a temporary
device can be identified by setting its ping interval on the screen of the LonMaker
for Windows tool device wizard shown in figure 7.7.

devices must respond to pinging before the Device Manager will indicate via its
status LED that all devices have been found.
