Automatic Writes To Devices (Isy99I Pro) - Universal Devices ISY-994i User Manual

The modem (PLM) is the communication bridge between the ISY and the INSTEON devices.
Without the modem and the links, you cannot control or get status from the INSTEON
devices. When the communication links were established via the Link Management Menu,
the PLM and INSTEON devices adds each device addresses it is linked to, in its own link
table. The ISY also stores the PLM's address.
If you need to remove a modem from your lighting network, select this function. It will
disconnect the ISY from the PLM and the PLM from all INSTEON devices in the network,
removing all the links between them. This ensures orphaned links do not exist in the
INSTEON devices when the PLM is removed from the lighting network. Also, it ensures the
ISY is not looking for the removed PLM.
Orphaned links are links between two devices where one is no longer in the network.
Orphaned links will affect the lighting network performance. A device with an orphaned
link to a missing PLM will create unnecessary network traffic by trying to communicate
with the PLM multiple times. This in effect will slow down the network response.
All ISY programs, Triggers or Schedules, will not work when you remove the modem from
the lighting network. Also, the actual status of all INSTEON devices will not be
synchronized with the status reported on the screen.

5.2.1.9Automatic Writes to Devices (ISY99i Pro)

By default, the ISY is set to automatically write updates to devices as you make changes in
the Admin Console. In some cases, you might prefer to queue your changes and write all
changes to devices at a more convenient time. Therefore, the PRO Series provides the
option to either write automatically or manually.
When this option is on, changes are written automatically to devices. Toggle this option off
to disable automatic writes. When toggled back on, all pending changes will be sent to
devices.
• If Automatic Writes to Battery Powered Devices is disabled those devices will not be
updated.
• At any time, you may write changes to a single device by selecting Write Updates to
Device from the device context menu.
• The ISY keeps track of all your changes, this determines when they will be written.
