The Trends Configuration page will only be displayed if this machine is configured as a Trends Server in the Project Editor.
Note: For a networked computer to be a Trends Server it needs to also be the I/O Server or needs to be able to communicate with the I/O Server on the network.
CitectSCADA has one option available for trend processing:
Inhibit triggered trends on startup
You might have a trend that is triggered off the rising edge of a bit on startup. If this option is enabled, the trends server does not display the trend until it has read the I/O Devices a second time.
