Werma WIN Ethernet

The Werma WIN system is a wireless communication system that makes machine state information available for digital processing. The system enables connectivity for stack lights and other industrial indicators. With Connectware, Werma WIN data can be easily integrated into your shop floor data structure.

System Overview

The Werma WIN system consists of several key components that work together to provide wireless industrial communication.

Werma WIN Ethernet Master

The master device acts as an access point for the wireless sensor network. It provides:

• Ethernet connectivity: The master's Ethernet port must be reachable by Connectware

• Network management: A single master manages access to multiple slave devices

• Data aggregation: Collects and forwards data from all connected slaves

To commission data acquisition, you must know the IP address of the Ethernet master.

Werma WIN Slave Devices

Each machine or stack light is equipped with a dedicated slave device. Key characteristics:

• Identification: Each slave is identified by its unique MAC address

• Discovery: MAC addresses can be discovered by inspecting Connectware logs or using the Werma WIN Windows Configuration tool

• Wireless communication: Communicates with the master via proprietary wireless protocol

Data Points

Every slave provides the following data points:

• RSSI: Signal strength indicator for the wireless connection between slave and master

• Tiers (t1, t2, t3, t4): State of up to four digital switches, typically associated with specific colors

  • Possible values: 'on', 'off', or 'blink'

Update Triggers

State updates from slaves can be triggered:

• At fixed time intervals

• On state changes of any tier (asynchronous)

Supporting Software

Werma WIN Easy Software

Required for system setup and configuration, including:

• Association between master and slave devices

• Network configuration

• Device management

This Windows-based software is shipped with the hardware.

Werma WIN Shop Floor Manager

Werma's proprietary shop floor management application can be used alongside Connectware. Since a Werma WIN Ethernet Master allows only one concurrent connection, use the Connectware Werma Proxy Service to distribute data to multiple applications simultaneously.

Protocol Integration

The Connectware Werma protocol maps the proprietary Werma WIN Protocol into MQTT/JSON format for seamless integration.

Service Commissioning File Example

The following example demonstrates how to configure a Werma connection and endpoint that subscribes to a device by its MAC address:

wermaConnection:
  type: Cybus::Connection
  properties:
    protocol: Werma
    connection:
      host: !ref host
      port: !ref port
      password: !ref password
      connectionStrategy:
        initialDelay: 1000
        maxDelay: 10000
        incrementFactor: 2

wermaSubscribe:
  type: Cybus::Endpoint
  properties:
    protocol: Werma
    connection: !ref wermaConnection
    subscribe:
      mac: !ref macAddress

Data Formats

Tier Data

Individual tier state information:

{
  "timestamp": "<unix timestamp in ms>",
  "value": "'on'|'off'|'blink'"
}

RSSI Data

Signal strength information:

{
  "timestamp": "<unix timestamp in ms>",
  "value": "<float>"
}

Complete Device Data

All data points from a single device:

{
  "timestamp": "<unix timestamp in ms>",
  "value": {
    "t1": "'on'|'off'|'blink'",
    "t2": "'on'|'off'|'blink'",
    "t3": "'on'|'off'|'blink'",
    "t4": "'on'|'off'|'blink'",
    "rssi": "<float>"
  }
}

Received Raw Data

Raw data is forwarded as received from the Werma WIN Ethernet master without additional processing or decoration.
