Platform daemon on a PC

When you install Niagara on your PC, one of the last “Would you like to?” install options is to Install and Start Platform Daemon.

The default selection is to install. You need the platform daemon locally installed and running to host a station on your local PC, such as for a Supervisor. This lets you open the Workbench client platform connection to your local (My Host) platform. It also allows remote client platform connections to your PC.

 NOTE: In Niagara 4.4 and later, the installation wizard provides the default daemon user home location which you can change if you wish. In the step to select the Daemon user home location you have the option to either accept the default location or specify a different location. 

Once installed and started on a PC, you can see the platform daemon listed as a Service from the Windows Control Panel, by selecting Administrative Tools > Services.

 NOTE: Alternatively, after Niagara installation on your PC, you can install and start the platform daemon at any time, if needed. From the Windows Start menu, do this with Start > All Programs > .n.n > Install Platform Daemon (shortcut for “plat.exe installdaemon”). 

In summary, your Workbench PC’s local platform daemon is not necessary for making client platform connections to other hosts, only to provide the ability to run a station locally on your PC.
