GPS position (RTU3031C)

Function
The block checks whether a specified setpoint position has been reached. The system
checks whether the setpoint position is within the configured radius.
Optionally, the block outputs the calculated distance between the determined position of the
GPS module of the RTU and the setpoint position.
If you select the "System location" setting for the "Position" parameter, the RTU uses the
geographical position configured on the "System" WBM page as the setpoint. With the
"Manual" setting, setpoints can be entered manually. With the "Variable" setting, the
coordinates at the "Latitude" and "Longitude" inputs are used as setpoints. If no permissible
values are present at the block via these inputs, the "Error" output is set.
The last received GPS position remains stored in the process image of the RTU even in
case of reception problems and is used for calculations. However, the "Max. age of the last
position" parameter can be used to limit or display the evaluation of the last known position.
If the age of the last known position exceeds the specified value, the "Error" output is set.
