ioLogik E4200 Using the Built-in Web Console
4-6
The following example illustrates configuring a Digital Output channel:
You may use the PowerOn Value field to specify the channel’s settings when the ioLogik system is powered
on, and the Safe Status Setting field to specify channel’s settings when the ioLogik system enters Safe Status.
Note that Safe Status is controlled by the Host Connection Watchdog, which is disabled by default. If the Host
Connection Watchdog is disabled, the ioLogik system will never enter Safe Status and your Safe Status settings
will have no effect.
