## What is SignalSim?

SignalSim – The Official Simulator for the NAST Automation 5 LED Smart Signal Tower

Planning to integrate a PATLITE signal light into your Universal Robots cobot cell?
SignalSim lets you fully test the signal tower's functionality – before purchasing
the hardware.

——— HOW DOES IT WORK? ———

The app connects via TCP/IP to your UR robot controller (with the NAST Automation
URCap installed incl. test key). All control commands that the URCap would
send to a real PATLITE signal tower are received by SignalSim and displayed as a
visual simulation in real time.

——— WHAT IS SIMULATED? ———

→ 5 LED segments with configurable signal colors
   (Red · Yellow · Yellow-Green · Green · Blue · White · Magenta)
→ Flash function per segment
→ Buzzer indicator
→ Status feedback to the robot controller
→ Clear command (reset all LEDs)

——— REQUIREMENTS ———

→ Universal Robots cobot with PolyScope 5 or PolyScope X
   (UR Series: UR8L · UR15 · UR18 · UR20 · UR30 | e-Series: UR3e · UR7e · UR12e · UR16e)
→ NAST Automation URCap incl. test key
   (available free of charge at nast-automation.de)
→ Wi-Fi connection on the same network as the robot
→ iOS 15 or later

——— WHO IS THIS APP FOR? ———

→ System integrators looking to demonstrate the signal solution to customers
→ Production planners who want to validate the UR integration upfront
→ End customers and prospects evaluating before purchasing
→ URCap developers who want to test without physical hardware

——— ABOUT NAST AUTOMATION ———

NAST Automation is a UR+ developer of Universal Robots.
The 5 LED Smart Signal Tower is available in the official UR Marketplace and is
delivered including the URCap.

The URCap incl. test key is available free of charge at nast-automation.de.
