RSSI graph
The graph shows the course of the measured radiated power(dBm value) of the selected
antenna over time (black line) and the RSSI values of all selected transponders (colored
lines/dots). Using the icons, you can modify the display of the graph and adapt it to your
needs.

Icon
In the "Recording time" input box, you can specify the duration of the recording shown in the
graph. With the aid of the gray shift bar, you can move the recording time of the draft
forwards or backwards.
The current RSSI value of the last selected transponder or the number of valid transponders
is also displayed as a numerical value. You can control the value that is displayed using the
radio buttons. Using the arrow symbols, you can expand or reduce the window for the
numeric RSSI value.
Digital inputs/outputs
In this area you can have these statuses of the digital inputs/outputs displayed. Inputs on a
gray background indicate that the inputs are either not connected or that no signal with the
minimum voltage is applied (see also the section "Connection scheme for the digital I/O
interface" of the system manual "SIMATIC RF600"). Outputs shown on a gray background
indicate that the output is logically set to the value "0" or is turned off. If an input or an output
is shown on a green background, this indicates logical status "1" or that the output is turned
on or that a signal is applied to the input.
You can use this function to control the outputs. To make changes, you need to click the
"Apply" button.
