8.3 Charge Point Network Profiles

Each network profile entry defines a complete connection profile, including:

OCPP URL
Security profile
Certificate paths
Timeout settings
Network interface
VPN configuration
APN configuration

Multiple profiles can be configured for different environments:

Slot 0: Production CSMS
Slot 1: Plugfest or test environment
Slot 2: OCTT cloud
Slot 3: Backup CSMS

The following example shows configurationSlot 0:

{
  "configurationSlot": 0,
  "connectionData": {
    "ocppVersion": "OCPP20",
    "ocppTransport": "JSON",
    "ocppCsmsUrl": "ws://497877863b54bfd9.octt.openchargealliance.org:16968/MCHP00002",
    "messageTimeout": 30,
    "securityProfile": 0,
    "ocppInterface": "Wired0",
    "vpn": { ... },
    "apn": { ... }
  },
  "caFile": "/path/.../cert.pem",
  "clientCertFile": "/path/.../client.pem",
  "clientKeyFile": "/path/.../private.key"
}


Field	Description

`messageTimeout`	Timeout, in seconds, for request-response pairs
`securityProfile`	`0`: No security `1`: Password-based authentication `2`: Server-side authentication `3`: Full TLS client and server authentication
`ocppInterface`	Network interface to use, such as `Wired0` or `Wireless0`
`vpn`	Optional VPN settings, including the server, authentication, and tunnel type
`apn`	Optional APN and cellular-modem settings
`caFile`	Root CA certificate used to validate the CSMS certificate during the TLS handshake
`clientCertFile`	Client certificate required for Security Profile 3
`clientKeyFile`	Private key associated with the client certificate
