I manually added a device to my network, but why when I execute a network browse does it disappear from the screen?

FactoryTalk Linx

comprises a browse cycle like

RSLinx Classic

, which scans addresses and determines the present devices. During each cycle,

FactoryTalk Linx

compares the list of devices present in its configuration for that network (discovered during a previous browse cycle or manually added to the network) against what was just discovered.

If a device is present in the configuration but was not found during the browse cycle, it is removed from the display. Thus, when browsing a network, the display shows the set of devices discovered during the most recent browse cycle.

If a device was manually added, though, then it has not actually been removed from the configuration; it has merely been removed from the display. To bring the manually-added device back into view, right-click on the network and click

Show All Devices
