Weigl Lift Control

Use cases

• Monitor door status, travel direction, and cabin position on a live cloud dashboard for each elevator.
• Create an alert when the emergency alarm or fire mode activates so building management is notified immediately.
• Track lift error counts over time to schedule preventive maintenance before breakdowns occur.
• Send floor-level travel commands remotely to test elevator operation after a service visit.
• Log cabin position data in millimeters to verify correct floor leveling across all 30 floors.
• Monitor cabin light status to coordinate lobby and surrounding area lighting automation.

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same IP network as the Weigl elevator controller via Ethernet.
2. 2Confirm that the Weigl controller is running WST Control firmware v1.7.0 or higher, or that you are using a Vitmax ECO unit.
3. 3Note the IP address and Modbus TCP port of the Weigl controller and enter these in the ModbusCloud gateway configuration.
4. 4Import the Weigl Lift Control template from the ModbusCloud template library and assign it to the configured connection.
5. 5Verify that read registers return valid data, paying special attention to address 0 where function code distinction may be needed for Lift Error (uint16) and Current Position (int16).
6. 6Test a level call by writing to a coil register for a specific floor and door side, then confirm the elevator responds correctly.

Things to watch for

01

Why do I get conflicting values for Lift Error and Current Position?

Both registers share address 0 but use different data types (uint16 for Lift Error, int16 for Current Position). Ensure you are using the correct Modbus function codes to distinguish between them. Check the Weigl documentation for the exact function code mapping.

02

What firmware version is required on the WST Control?

The Modbus TCP interface requires WST Control firmware version 1.7.0 or higher. The Vitmax ECO is supported without a specific firmware requirement noted. Contact Weigl support if you are unsure about your firmware version.

03

How is the cabin position value reported?

Current Position is reported in millimeters as a signed 16-bit integer (int16). You can use this value to verify accurate floor leveling or to display the cabin location on your dashboard.

04

How many write registers does the template use for floor calls?

The template uses 128 coil-style write registers in total. Each of the 30 floors has four registers, one per door opening side (0, 90, 180, and 270 degrees). The remaining registers cover the full allocation up to 128.
