In general, there are two possibilities to realize a distance/status display with the SLT and the SIG200.
Possibility 1: SLT "fills up" depending on the distance
The following points are to be done:
Setup SLT:
Process data to "Level Meter Mode"
Adjust lights: Colors and Style (continuos or flashing) of the segments
Setup SIG200:
Upload IODD and assign to the correct ports
Connect devices
Edit Logic editor -> we need to convert the distance for "Level Meter Mode" into values between 0 and 100.
Possibility 2: SLT as a status indication
Application example: We want to display 4 different areas:
green: dist > 2000 mm
yellow: 2000 mm > dist > 1000 mm
red flashing: 1000 mm > dist > 10 mm
red: dist < 10 mm
We can use the "alarm indication" with the SLT. For this, profiles for 3 alarms can be selected (colors can be defined flexibly for each profile). We can then specify which profile is to be displayed with a 1, 2 or 3 on the variable. For the 4th section, we can use the "Signal lamp mode" of the SLT and make all the tier's flashing red.
The following points are to be done:
Setup SLT:
Process data to "Signal lamp mode"
Adjust lights: Colors and Style (continuous or flashing) of the segments and define the alarm profiles
Setup SIG200:
Upload IODD and assign to the correct ports
Connect devices
Edit Logic editor -> we need to switch the alarm indication depending of the distance to 1, 2 or 3. Also we have to set Tier 1-5 on if the distance is in a specific range.

One purpose of the retrofit was to visualize the fill level of the two used adhesive cartridges by using MPA sensors and SLT signal lights. The second purpose was to detect the presence of a sensor housing, a PCB and a heat shield by using a single energetic W4 sensor (described in another tutorial). The application's logic circuitry was created using two SIG200s with built-in logic editors and one SIG100 as a port extension. Using the SIG200s enables a future upgrade to I4.0 applications e.g., monitoring with the Field Analytics software or SD3 (Sick Dynamic Data Display).
