Communication-capable Circuit Breakers

WL Circuit Breaker

The write-protect function ensures that all the required information can be transmitted, but prevents any changes to the status of the circuit breaker. Changes can then only be made locally.

Why does the write protection function permit certain actions?

All actions that are not blocked are for remote analysis only and do not have any effect on the current status.

Data Exchange via the COM16 Module

When the COM16 module is configured to exchange data, it is important to note that it is shipped as standard with MODBUS address 126. This can be changed during system configuration (e.g. with the BDA, WinPM.Net, WL Config software or ETU776 display).

The COM16 module has two LEDs (MODBUS and CubicleBUS) for diagnostic purposes. These indicate the operating status of the communication line and the CubicleBUS networks.

Two LEDs are used to determine whether a CubicleBUS module in the circuit breaker is operational. First, the "COMM" LED on the trip unit must be green, that is, the trip unit has recognized at least one other CubicleBUS module. At a minimum, this would only be the Metering Function PLUS if the CubicleBUS was then interrupted. Second, the CubicleBUS LED on the COM16 module must be taken into account. If this is lit with a steady green light, a connection exists from the COM16 module to at least the metering function Plus module.

If both LEDs are green (steady light for CubicleBUS on the COM16 module and COMM on the trip unit), communication is fully established between the trip unit and the COM16 module.

Data is exchanged according to the following principle: an up-to-date copy of all WL Circuit Breaker data (apart from the waveform buffer) is always stored in the COM16 module. A response to a data query from the COM16 module to the supervisory system can, be typically transmitted in just a few milliseconds. Write data from the supervisory system is forwarded to the appropriate addressee on the CubicleBUS.
