PLC systems often use addresses such as X0, X1, Y0, and Y5 to represent inputs and outputs.
While these addresses are useful for programmers, they can make installation and troubleshooting difficult for technicians who do not have access to the original PLC program.
To solve this problem, we developed a PLC status screen that converts these addresses into descriptive text and displays their real-time ON/OFF status.
Examples include:
Upper limit switch — ON
Door signal — OFF
Motor running — ON
This allows installers and maintenance personnel to quickly understand machine conditions without connecting programming software.
The system is suitable for:
✔ Home lifts
✔ Freight elevators
✔ Scissor lifts
✔ Hydraulic lifting equipment
In our experience, clear text information is often more useful than complicated graphical interfaces when performing maintenance and troubleshooting.
