Documentation
OCPP
Via the OCPP protocol, wallboxes can be conveniently monitored and switched via Symcon.
scope of functions
- Display of consumption of individual charging points
- Display of whether a transaction is currently in progress for charging points
- Enable charging process via Id Tag, typically RFID card
software installation
- Install the 'OCPP' module via the Module Store.
- Under 'Add instance' the 'OCPP Configurator' module can be found using the quick filter.
- Further information on adding instances in the Instance documentation
- On the configuration page of the splitter, the information for setting up a charging point can be taken.
Depending on the wallbox, the parameters must be specified individually or as a complete URL. - Once the connection is established, the charging points are displayed in the configurator and can be created.
Configuration page (Charging Point)
| Name | Description |
|---|---|
| Charge Point Identity | Identifier of the charging station |
| Start transaction... | Defines when the charging process should be started automatically: "... automatically on connection": The charging process is started directly when a vehicle is connected. "... when an Id Tag is validated - Allow all Id Tags": The charging process is started when any Id Tag is scanned. The tag itself is not further validated. "... when an Id Tag is validated - Allow only Central Id Tag list": The charging process is started when an Id Tag from the central Id Tag list is scanned. This list can be configured in the splitter. "... when an Id Tag is validated - Allow only Local Id Tag list": The charging process is started when an Id Tag from the local Id Tag list is scanned. This list can be configured directly below this selection. "... when an Id Tag is validated - Allow both Id Tag lists": The charging process is started when an Id Tag from the local or central Id Tag list is scanned. The local list can be configured directly below this selection and the central list in the splitter. |
| Local list of valid Id Tags (e.g. RFID cards) | The local list for Id Tags at which the charging process should be started. In addition to the Id Tag, first name, last name, e-mail and general information about the Id Tag can be specified. These help to assign the tag. (Only displayed if "Start transaction..." is set to "... when an Id Tag is validated - Allow only Local Id Tag list" or "... when an Id Tag is validated - Allow both Id Tag lists".) |
Configuration page (Splitter)
| Name | Description |
|---|---|
| Central list of valid Id Tags (e.g. RFID cards) | The central list for Id Tags which can be used to automatically start the charging process. In addition to the Id Tag, first name, last name, e-mail and general information about the Id Tag can be specified. These help to assign the tag. |
Notes
- The exact Id Tags of an RFID card can be determined by scanning it once at the charging station. The Id Tag can then be taken from the status variable "Last Id Tag".
- For the Pulsar Plus, all schedules must be removed before activating OCPP. Control via OCPP cannot overwrite the configured time schedules, as these always have priority.
status variables: charging point
General Status Variables
These status variables exist once, independent of the connectors of the charging point.
| Name | Type | Description |
|---|---|---|
| Vendor | string | Name of the manufacturer |
| Model | string | Model of the charging point |
| Serial Number | string | Serial number of the charging point |
| Last Id Tag | string | Last read Id Tag |
Status Variables per Connector
A charging point can manage multiple connectors. In this case, each connector may create its own status variables. These are created at runtime based on the interaction with the connector. Therefore, not all variables must exist.
| Name | Type | Description |
|---|---|---|
| Meter Value | float | The meter reading of the connector |
| Available | boolean | The availability of the connector - If the connector has been set to unavailable, charging is not possible there |
| Status | string | Current status of the connector |
| ErrorCode | string | Current error code, "" if there is currently no error |
| Transaction | boolean | If true, a transaction is active, so the connected vehicle is being charged. |
| Transaction Id | integer | ID of the current or last transaction |
| Transaction Meter Start | integer | Meter reading in Wh at the start of the current or last transaction |
| Transaction Meter End | integer | Meter reading in Wh at the end of the current or last transaction |
| Transaction Id Tag | string | Id Tag of the current or last transaction |
| Transaction Consumption | integer | Energy consumption in Wh of the current or last transaction |
