Site topology

Purpose​

In order to configure the topology of a site in the Fuzz Local Controller, some information about the installation and the equipment must be known.

This information is used to define the site assets, their electrical characteristics, and their communication settings.

General site information​

The following information is required to create the site configuration:

  • Project name
  • Single-line diagram of the installation, including in particular:
    • circuit breakers
    • switchboards
    • busbar capacity
    • charge point power ratings
  • Local Controller IP address
    • static IP recommended
    • DHCP possible if no OCPP asset is used

Information to provide for each asset​

Every piece of equipment present on the site must be described in the configuration.

General information​

  • Asset name

  • Asset type

    • charge point
    • switchboard
    • meter
    • photovoltaic
    • battery
    • wind turbine

  • Brand and model

Examples:

  • Phoenix Contact EEM‑MA371

  • Alfen Sline 11kW Cable

  • Huawei Smartlogger

  • Maximum current per phase

Example: 32 / 32 / 32 A

  • Phase mapping

Used to indicate the correspondence between the grid phases and those of the equipment.

Examples: (L1/L2/L3) (L2/L3/L1) (L3/L1/L2)

Example: (L3/L1/L2) means:

  • Asset L1 → Grid L3
  • Asset L2 → Grid L1
  • Asset L3 → Grid L2

Type-specific information​

Modbus assets​

Equipment can communicate with the Local Controller via Modbus TCP or Modbus RTU (RS485).

Modbus TCP​

  • IP address
  • Modbus ID
  • Modbus port (default: 502)

Modbus RTU (RS485)​

  • communication interface used (Serial 1, Serial 2 or USB)
  • serial port
  • Modbus ID
  • baud rate
  • parity
  • data bits
  • stop bits

OCPP charge points​

  • OCPP ID
  • CPO URL (if applicable)
  • charging authorization method

Possible values:

  • Plug&Charge
  • LocalController
  • CPO
  • LocalControllerThenCPO

Assets with a web interface​

Some equipment has a web interface accessible on the local network.

Required information:

  • local IP address
  • protocol: HTTP or HTTPS
  • port (if different from the default ports)

Default ports:

  • HTTP: 80
  • HTTPS: 443
