Everyware Software Framework Developer's Hub

Everyware Software Framework (ESF) is an enterprise-ready IoT Edge Framework distributed and supported by Eurotech. Based on Eclipse Kura, the open source Java/OSGi middleware for IoT gateways, ESF adds provisioning, advanced security, remote access, diagnostics monitoring. It supports ready-to-use field protocols (including Modbus, OPC-UA, S7, FANUC, J1939, J1979, BACnet, IEC 60870-5-101, IEC 60870-5-104, DNP3, M-bus), MQTT connectivity, and a web-based visual data flow programming to acquire data from the field, process it at the edge, and publish it to IoT Cloud Platforms. ESF features full remote device management through its integration with Everyware Cloud, Eurotech’s IoT Integration Platform.

Get Started

MBus Driver

This driver provides support for interacting with MBus slaves using the Driver and Asset models.
Features:

  • Meter readout in the JSON format
  • Bus scanning
  • Support for primary and secondary addressing

📘

Note

It is not possible to connect the serial ports of Eurotech gateways to a MBus network directly. Connection should be made using an external MBus level converter with echo suppression.

Global driver configuration

The driver global configuration contains parameters related to the connection. The relevant parameters depend on the mode.

Serial mode

For establishing an serial connection, the following parameters are relevant:

  • Connection mode must be set to SERIAL

  • Serial port name should be set to the desired used serial port device (e.g. /dev/ttyO3)

  • Serial baud rate

  • Serial data bits

  • Serial stop bits

  • Serial parity

IP mode

For establishing an IP connection, the following parameters are relevant:

  • Connection mode must be set to IP

  • IP address should be set to the remote hostname or IP address

  • IP port number

Channel configuration

The driver support the following modes for READ channels configurable by the Read mode channel parameter, the meaning of the other parameters depends on the channel mode:

  • READ: Reads a specific slave addressed using either the primary or secondary address.

    • Primary address: If this parameter is set to a non-zero value, it specifies the primary address of the slave. If set to 0, the Secondary address parameter will be used.

    • Secondary address: A JSON object that defines the secondary address of the slave to read. The format of the JSON object is described in the SecondaryAddressIn section. The secondary address can contain wildcards.

    The result will contain as a JSON array of VariableDataStructure objects, one for each frame received from the slave.

  • SCAN: Discovers the secondary addresses of the devices connected to the bus.

    • Primary address: Must be set to 0

    • Secondary address: A JSON object that defines the mask to be used for scanning. The format of the JSON object is described in the SecondaryAddressIn section. The secondary address should contain wildcards.

    The result will contain as a JSON array of SecondaryAddressOut objects, one for each discovered slave.

  • SCAN_AND_READ: Discovers the secondary addresses of the devices connected to the bus and performs a read on each discovered device.

    • Primary address: Must be set to 0

    • Secondary address: A JSON object that defines the mask to be used for scanning. The format of the JSON object is described in the SecondaryAddressIn section. The secondary address should contain wildcards.

    The result will contain as a JSON array of SecondaryAddressOut objects, one for each discovered slave.

In all cases the value.type parameter must be set to STRING as the driver will use the JSON format for channel output.

JSON representation

This section describes the JSON format used by the driver for input and output data. It is recommended to check output data for missing and/or null fields, that might be present if decoding slave responses fail.
