### Function description

\
This function block allows reading out the system information.\
The static values that are written to the controller when an application is downloaded are displayed.\
In addition, values that can change at runtime of the runtime are also displayed.\
These values can be queried at a definable interval and, if necessary, also read out.

#### Input *xGetNetworkInfo*

\
On each rising edge (FALSE > TRUE) the current network information of the system is read out.\
The return of the values is done via the outputs **sEthernetAdapterIPAddress**, **sEthernetAdapterSubnetMask**, **sEthernetAdapterGateway** and **sEthernetAdapterMACAddress**.

#### Input *xGetRTUpTime*

\
On each rising edge the current uptime of the system is read out.\
The return of the value is done via the output **tRuntimeUptime**.
