The ODS runs on a computer platform and is installed within the Metasys network. With an ODS, you can provide a location to install the SCT and a location to send trend logs (Trend Studies), event logs (Alarm and Event Management), and audit trails (Audit Trail). The ODS can also be configured to take the role of the Site Director to coordinate system access and present data to the user in a web browser running on the same computer or connected over the LAN, WAN, Internet, or telephone line through a dial-up connection.
Notes:
- Online/offline modes as explained here do not apply to the ODS. However, the ODS can be online and offline in the same sense as any other device on the network can be connected or disconnected from the network.
- You may need to change the Windows Defender tool settings on your operating system (OS) when using an ODS. Windows Defender is a spyware identification and removal tool that is part of the OS. For Windows 10, Windows 8.1, and Windows 8, this tool is on by default. For Windows Server 2016, Windows Server 2012 R2, and Windows Server 2012, this tool is off by default. Windows Defender scans the OS for spyware every night at 2 A.M. If you expect heavy use of the ODS at this time (for example, due to trend collection), reschedule the scan to a time when the ODS is not as active.
- You may need to change the Disk Defragmentation settings on your OS when using an ODS. Disk Defragmentation is scheduled to run by default every Wednesday at 1 A.M. If you expect heavy use of the ODS at this time (for example, due to trend collection), reschedule the scan to a time when the ODS is not as active.
- You should not add an ODS as a child device under an ADS or ADX. The ODS should always be the parent device to child NAEs.
