Communication-capable Circuit Breakers

WL Circuit Breaker

Supervisory Systems

The WL Circuit Breaker supports the industry standard MODBUS protocol through the COM16 interface.

Communication connections to the COM16 are made through the DB-9 port on the front of the COM16; see Graphic 3-2 for connecting cable pin assignments. Typically the communication wiring from the COM16 will be installed at the factory and run to communication terminal blocks in the switchgear. At these terminal blocks customers can connect twisted shielded pair RS 485 cable to Ethernet Converters, MODBUS Masters, PLCs or supervisory control systems. When the WL Circuit Breaker is installed in Siemens switchgear as part of an ACCESS power monitoring system, the default wiring will be through a Siemens power meter Ethernet gateway or Ethernet converter

connected to a WinPM.Net workstation. For customers with existing MODBUS networks or who require integration into a MODBUS system the following information can be used to develop a software interface to the WL / COM16.

Data in the COM16 is organized in what is referred to as “Datasets”. Each dataset contains a group of functionally common registers. For instance all metered data is organized in a dataset, which consists of 119 registers, min./max. information in another dataset, and diagnostic information in another dataset. In all, the COM16 has a total of 28 datasets, which can be read via communication. Users can take advantage of this structure and ask for blocks of data in one message request, making integration into MODBUS system fast and efficient. The COM16 also

supports pre-configured or standard register maps for simple data interfacing. Users can define what types of data they want in any of three default register sets. Type 1 provides 4 default registers. Type 2 provides 8 registers, and Type 3 provides 14 registers, all in consecutive order for easy requests. The WL is included in WinPM.Net and can be configured remotely using the software or using the remote set-up tool, WL Config.

Each register includes a corresponding status register, which can be read in order to validate the real-time data. This register is referred to as the property byte.

Graphic 3-1Siemens Power Monitoring and control software WinPM.Net communicates to multiple device types using Ethernet, modem and RS 485 serial networks. The integration of the WL Circuit Breaker into WinPM.Net is a key component of totally integrated power.
