Configuring Charge Point Operator Supervisions

To configure charge point operator supervisions:

Select ADMIN > Configuration > Remote Supervision.
Select your type of EcoStruxure EV Charging Expert supervision:
- Local: EcoStruxure EV Charging Expert is managing authentication rules and badges.
- Unique: one supervision is managing authentication rules and badges of the complete installation.
- Multiple: charging stations are divided in groups managed by a specific supervision or by EcoStruxure EV Charging Expert.

NOTE: Between the charging stations and the remote supervision, the communication protocol must be OCPP 1.6 Json.

For Unique Supervision

Select Unique and Save.
Enter the Remote Supervision URL Address: WebSocket (ws) or WebSocket Secure (wss). It is recommended to use a WebSocket Secure as a good practice of cybersecurity, and to add a certificate if needed.
Websocket Ping Interval: positive values are interpreted as number of seconds between pings. The value must be between 1 and 60 seconds.
Message timeout: interval between request and response OCPP message before considering the connection lost. The value must be between 1 and 60 seconds.
Forward security event to CPO: OCPP security events.
Select Save.

For Multiple Supervisions

Select Multiple.
To add your supervisions, select the + sign.
To configure each supervision, follow steps 2 to 6 described in the process for a unique supervision.

Multiple supervisions option offers the possibility to manage authentication strategy according to supervision or local strategy. To manage the installation, it is necessary to create authentication groups and assigned charging stations to a group. An authentication group is a selection of charging stations associated to a charging point operator.

There are two charging point operator options:

Supervision as charging point operator: select in the list the supervision already configured.
Local as charging point operator. For detailed information, see Managing Authentication.

IMPORTANT: When remote supervision option is enabled:

It is the responsibility of the remote supervision system to handle EV driver authentication and to consider charging station specific keys for authentication management.
The date and time are provided by the Charging Station Management System, but it is necessary to configure the time zone.
